@noqa " Marseille, France (CNN)The French prosecutor leading an investigation into the crash of Germanwings" " Flight 9525 insisted Wednesday that he was not aware of any video footage from on board the plane." ' Marseille prosecutor Brice Robin told CNN that "so far no videos were used in the crash investigation."' ' He added, "A person who has such a video needs to immediately give it to the investigators." Robin\'s' " comments follow claims by two magazines, German daily Bild and French Paris Match, of a cell phone video" " showing the harrowing final seconds from on board Germanwings Flight 9525 as it crashed into the French" " Alps. All 150 on board were killed. Paris Match and Bild reported that the video was recovered from a" " phone at the wreckage site. The two publications described the supposed video, but did not post it on" " their websites. The publications said that they watched the video, which was found by a source close to" " the investigation. \"One can hear cries of 'My God' in several languages,\" Paris Match reported." ' "Metallic banging can also be heard more than three times, perhaps of the pilot trying to open the' " cockpit door with a heavy object. Towards the end, after a heavy shake, stronger than the others, the" ' screaming intensifies. Then nothing." "It is a very disturbing scene," said Julian Reichelt,' " editor-in-chief of Bild online. An official with France's accident investigation agency, the BEA, said" " the agency is not aware of any such video. Lt. Col. Jean-Marc Menichini, a French Gendarmerie spokesman" " in charge of communications on rescue efforts around the Germanwings crash site, told CNN that the" ' reports were "completely wrong" and "unwarranted." Cell phones have been collected at the site, he said,' ' but that they "hadn\'t been exploited yet." Menichini said he believed the cell phones would need to be' " sent to the Criminal Research Institute in Rosny sous-Bois, near Paris, in order to be analyzed by" " specialized technicians working hand-in-hand with investigators. But none of the cell phones found so" " far have been sent to the institute, Menichini said. Asked whether staff involved in the search could" ' have leaked a memory card to the media, Menichini answered with a categorical "no." Reichelt told "Erin' ' Burnett: Outfront" that he had watched the video and stood by the report, saying Bild and Paris Match' ' are "very confident" that the clip is real. He noted that investigators only revealed they\'d recovered' ' cell phones from the crash site after Bild and Paris Match published their reports. "That is something' " we did not know before. ... Overall we can say many things of the investigation weren't revealed by the" ' investigation at the beginning," he said. What was mental state of Germanwings co-pilot? German airline' " Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled depression years before he took the" " controls of Germanwings Flight 9525, which he's accused of deliberately crashing last week in the" ' French Alps. Lubitz told his Lufthansa flight training school in 2009 that he had a "previous episode of' ' severe depression," the airline said Tuesday. Email correspondence between Lubitz and the school' " discovered in an internal investigation, Lufthansa said, included medical documents he submitted in" " connection with resuming his flight training. The announcement indicates that Lufthansa, the parent" " company of Germanwings, knew of Lubitz's battle with depression, allowed him to continue training and" " ultimately put him in the cockpit. Lufthansa, whose CEO Carsten Spohr previously said Lubitz was 100%" ' fit to fly, described its statement Tuesday as a "swift and seamless clarification" and said it was' " sharing the information and documents -- including training and medical records -- with public" " prosecutors. Spohr traveled to the crash site Wednesday, where recovery teams have been working for the" " past week to recover human remains and plane debris scattered across a steep mountainside. He saw the" " crisis center set up in Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash" " site, where grieving families have left flowers at a simple stone memorial. Menichini told CNN late" " Tuesday that no visible human remains were left at the site but recovery teams would keep searching." " French President Francois Hollande, speaking Tuesday, said that it should be possible to identify all" " the victims using DNA analysis by the end of the week, sooner than authorities had previously suggested." " In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini said." " Among those personal belongings could be more cell phones belonging to the 144 passengers and six crew" " on board. Check out the latest from our correspondents . The details about Lubitz's correspondence with" " the flight school during his training were among several developments as investigators continued to" " delve into what caused the crash and Lubitz's possible motive for downing the jet. A Lufthansa" " spokesperson told CNN on Tuesday that Lubitz had a valid medical certificate, had passed all his" ' examinations and "held all the licenses required." Earlier, a spokesman for the prosecutor\'s office in' " Dusseldorf, Christoph Kumpa, said medical records reveal Lubitz suffered from suicidal tendencies at" " some point before his aviation career and underwent psychotherapy before he got his pilot's license." " Kumpa emphasized there's no evidence suggesting Lubitz was suicidal or acting aggressively before the" " crash. Investigators are looking into whether Lubitz feared his medical condition would cause him to" " lose his pilot's license, a European government official briefed on the investigation told CNN on" ' Tuesday. While flying was "a big part of his life," the source said, it\'s only one theory being' " considered. Another source, a law enforcement official briefed on the investigation, also told CNN that" " authorities believe the primary motive for Lubitz to bring down the plane was that he feared he would" " not be allowed to fly because of his medical problems. Lubitz's girlfriend told investigators he had" " seen an eye doctor and a neuropsychologist, both of whom deemed him unfit to work recently and concluded" " he had psychological issues, the European government official said. But no matter what details emerge" " about his previous mental health struggles, there's more to the story, said Brian Russell, a forensic" ' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the fact' " that maybe they weren't going to keep doing their job and they're upset about that and so they're" ' suicidal," he said. "But there is no mental illness that explains why somebody then feels entitled to' " also take that rage and turn it outward on 149 other people who had nothing to do with the person's" ' problems."

The" " formal accession was marked with a ceremony at The Hague, in the Netherlands, where the court is based." " The Palestinians signed the ICC's founding Rome Statute in January, when they also accepted its" ' jurisdiction over alleged crimes committed "in the occupied Palestinian territory, including East' ' Jerusalem, since June 13, 2014." Later that month, the ICC opened a preliminary examination into the' " situation in Palestinian territories, paving the way for possible war crimes investigations against" " Israelis. As members of the court, Palestinians may be subject to counter-charges as well. Israel and" " the United States, neither of which is an ICC member, opposed the Palestinians' efforts to join the" " body. But Palestinian Foreign Minister Riad al-Malki, speaking at Wednesday's ceremony, said it was a" ' move toward greater justice. "As Palestine formally becomes a State Party to the Rome Statute today, the' ' world is also a step closer to ending a long era of impunity and injustice," he said, according to an' ' ICC news release. "Indeed, today brings us closer to our shared goals of justice and peace." Judge' " Kuniko Ozaki, a vice president of the ICC, said acceding to the treaty was just the first step for the" ' Palestinians. "As the Rome Statute today enters into force for the State of Palestine, Palestine' " acquires all the rights as well as responsibilities that come with being a State Party to the Statute." ' These are substantive commitments, which cannot be taken lightly," she said. Rights group Human Rights' ' Watch welcomed the development. "Governments seeking to penalize Palestine for joining the ICC should' " immediately end their pressure, and countries that support universal acceptance of the court's treaty" ' should speak out to welcome its membership," said Balkees Jarrah, international justice counsel for the' " group. \"What's objectionable is the attempts to undermine international justice, not Palestine's" ' decision to join a treaty to which over 100 countries around the world are members." In January, when' " the preliminary ICC examination was opened, Israeli Prime Minister Benjamin Netanyahu described it as an" ' outrage, saying the court was overstepping its boundaries. The United States also said it "strongly"' " disagreed with the court's decision. \"As we have said repeatedly, we do not believe that Palestine is a" ' state and therefore we do not believe that it is eligible to join the ICC," the State Department said in' ' a statement. It urged the warring sides to resolve their differences through direct negotiations. "We' ' will continue to oppose actions against Israel at the ICC as counterproductive to the cause of peace,"' " it said. But the ICC begs to differ with the definition of a state for its purposes and refers to the" ' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows the' " court to review evidence and determine whether to investigate suspects on both sides. Prosecutor Fatou" ' Bensouda said her office would "conduct its analysis in full independence and impartiality." The war' " between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The inquiry" " will include alleged war crimes committed since June. The International Criminal Court was set up in" " 2002 to prosecute genocide, crimes against humanity and war crimes.

Expect pushback anyway, if the recent past is any harbinger." " Just last month, in an attempt to head off such an agreement, House Speaker John Boehner invited Israeli" " Prime Minister Benjamin Netanyahu to preemptively blast it before Congress, and 47 senators sent a" " letter to the Iranian leadership warning them away from a deal. The debate that has already begun since" " the announcement of the new framework will likely result in more heat than light. It will not be helped" " by the gathering swirl of dubious assumptions and doubtful assertions. Let us address some of these: ." " The most misleading assertion, despite universal rejection by experts, is that the negotiations'" " objective at the outset was the total elimination of any nuclear program in Iran. That is the position" " of Netanyahu and his acolytes in the U.S. Congress. But that is not and never was the objective. If it" " had been, there would have been no Iranian team at the negotiating table. Rather, the objective has" " always been to structure an agreement or series of agreements so that Iran could not covertly develop a" " nuclear arsenal before the United States and its allies could respond. The new framework has exceeded" " expectations in achieving that goal. It would reduce Iran's low-enriched uranium stockpile, cut by" " two-thirds its number of installed centrifuges and implement a rigorous inspection regime. Another" " dubious assumption of opponents is that the Iranian nuclear program is a covert weapons program. Despite" " sharp accusations by some in the United States and its allies, Iran denies having such a program, and" " U.S. intelligence contends that Iran has not yet made the decision to build a nuclear weapon. Iran's" " continued cooperation with International Atomic Energy Agency inspections is further evidence on this" " point, and we'll know even more about Iran's program in the coming months and years because of the deal." " In fact, the inspections provisions that are part of this agreement are designed to protect against any" " covert action by the Iranians. What's more, the rhetoric of some members of Congress has implied that" " the negotiations have been between only the United States and Iran (i.e., the 47 senators' letter" " warning that a deal might be killed by Congress or a future president). This of course is not the case." " The talks were between Iran and the five permanent members of the U.N. Security Council (United States," " United Kingdom, France, China and Russia) plus Germany, dubbed the P5+1. While the United States has" " played a leading role in the effort, it negotiated the terms alongside its partners. If the agreement" " reached by the P5+1 is rejected by Congress, it could result in an unraveling of the sanctions on Iran" " and threaten NATO cohesion in other areas. Another questionable assertion is that this agreement" " contains a sunset clause, after which Iran will be free to do as it pleases. Again, this is not the" " case. Some of the restrictions on Iran's nuclear activities, such as uranium enrichment, will be eased" " or eliminated over time, as long as 15 years. But most importantly, the framework agreement includes" " Iran's ratification of the Additional Protocol, which allows IAEA inspectors expanded access to nuclear" " sites both declared and nondeclared.

All 150 on board were killed. Paris Match and Bild reported that the video was" " recovered from a phone at the wreckage site. The two publications described the supposed video, but" " did not post it on their websites. The publications said that they watched the video, which was" " found by a source close to the investigation. \"One can hear cries of 'My God' in several" ' languages," Paris Match reported. "Metallic banging can also be heard more than three times, perhaps' " of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy" ' shake, stronger than the others, the screaming intensifies. Then nothing." "It is a very disturbing' " scene,\" said Julian Reichelt, editor-in-chief of Bild online. An official with France's accident" " investigation agency, the BEA, said the agency is not aware of any such video. Lt. Col. Jean-Marc" " Menichini, a French Gendarmerie spokesman in charge of communications on rescue efforts around the" ' Germanwings crash site, told CNN that the reports were "completely wrong" and "unwarranted." Cell' ' phones have been collected at the site, he said, but that they "hadn\'t been exploited yet."' " Menichini said he believed the cell phones would need to be sent to the Criminal Research Institute" " in Rosny sous-Bois, near Paris, in order to be analyzed by specialized technicians working" " hand-in-hand with investigators. But none of the cell phones found so far have been sent to the" " institute, Menichini said. Asked whether staff involved in the search could have leaked a memory" ' card to the media, Menichini answered with a categorical "no." Reichelt told "Erin Burnett:' ' Outfront" that he had watched the video and stood by the report, saying Bild and Paris Match are' ' "very confident" that the clip is real. He noted that investigators only revealed they\'d recovered' ' cell phones from the crash site after Bild and Paris Match published their reports. "That is' " something we did not know before. ... Overall we can say many things of the investigation weren't" ' revealed by the investigation at the beginning," he said. What was mental state of Germanwings' " co-pilot? German airline Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled" " depression years before he took the controls of Germanwings Flight 9525, which he's accused of" " deliberately crashing last week in the French Alps. Lubitz told his Lufthansa flight training school" ' in 2009 that he had a "previous episode of severe depression," the airline said Tuesday. Email' " correspondence between Lubitz and the school discovered in an internal investigation, Lufthansa" " said, included medical documents he submitted in connection with resuming his flight training. The" " announcement indicates that Lufthansa, the parent company of Germanwings, knew of Lubitz's battle" " with depression, allowed him to continue training and ultimately put him in the cockpit. Lufthansa," " whose CEO Carsten Spohr previously said Lubitz was 100% fit to fly, described its statement Tuesday" ' as a "swift and seamless clarification" and said it was sharing the information and documents --' " including training and medical records -- with public prosecutors. Spohr traveled to the crash site" " Wednesday, where recovery teams have been working for the past week to recover human remains and" " plane debris scattered across a steep mountainside. He saw the crisis center set up in" " Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash site, where grieving" " families have left flowers at a simple stone memorial. Menichini told CNN late Tuesday that no" " visible human remains were left at the site but recovery teams would keep searching. French" " President Francois Hollande, speaking Tuesday, said that it should be possible to identify all the" " victims using DNA analysis by the end of the week, sooner than authorities had previously suggested." " In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini" " said. Among those personal belongings could be more cell phones belonging to the 144 passengers and" " six crew on board. Check out the latest from our correspondents . The details about Lubitz's" " correspondence with the flight school during his training were among several developments as" " investigators continued to delve into what caused the crash and Lubitz's possible motive for" " downing the jet. A Lufthansa spokesperson told CNN on Tuesday that Lubitz had a valid medical" ' certificate, had passed all his examinations and "held all the licenses required." Earlier, a' " spokesman for the prosecutor's office in Dusseldorf, Christoph Kumpa, said medical records reveal" " Lubitz suffered from suicidal tendencies at some point before his aviation career and underwent" " psychotherapy before he got his pilot's license. Kumpa emphasized there's no evidence suggesting" " Lubitz was suicidal or acting aggressively before the crash. Investigators are looking into whether" " Lubitz feared his medical condition would cause him to lose his pilot's license, a European" ' government official briefed on the investigation told CNN on Tuesday. While flying was "a big part' " of his life,\" the source said, it's only one theory being considered. Another source, a law" " enforcement official briefed on the investigation, also told CNN that authorities believe the" " primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly" " because of his medical problems. Lubitz's girlfriend told investigators he had seen an eye doctor" " and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had" " psychological issues, the European government official said. But no matter what details emerge about" " his previous mental health struggles, there's more to the story, said Brian Russell, a forensic" ' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the' " fact that maybe they weren't going to keep doing their job and they're upset about that and so" ' they\'re suicidal," he said. "But there is no mental illness that explains why somebody then feels' " entitled to also take that rage and turn it outward on 149 other people who had nothing to do with" " the person's problems.\" Germanwings crash compensation: What we know .

"Governments seeking to penalize' " Palestine for joining the ICC should immediately end their pressure, and countries that support" " universal acceptance of the court's treaty should speak out to welcome its membership,\" said" " Balkees Jarrah, international justice counsel for the group. \"What's objectionable is the attempts" " to undermine international justice, not Palestine's decision to join a treaty to which over 100" ' countries around the world are members." In January, when the preliminary ICC examination was' " opened, Israeli Prime Minister Benjamin Netanyahu described it as an outrage, saying the court was" ' overstepping its boundaries. The United States also said it "strongly" disagreed with the court\'s' ' decision. "As we have said repeatedly, we do not believe that Palestine is a state and therefore we' ' do not believe that it is eligible to join the ICC," the State Department said in a statement. It' ' urged the warring sides to resolve their differences through direct negotiations. "We will continue' ' to oppose actions against Israel at the ICC as counterproductive to the cause of peace," it said.' " But the ICC begs to differ with the definition of a state for its purposes and refers to the" ' territories as "Palestine." While a preliminary examination is not a formal investigation, it allows' " the court to review evidence and determine whether to investigate suspects on both sides. Prosecutor" ' Fatou Bensouda said her office would "conduct its analysis in full independence and impartiality."' " The war between Israel and Hamas militants in Gaza last summer left more than 2,000 people dead. The" " inquiry will include alleged war crimes committed since June.

Marseille prosecutor" ' Brice Robin told CNN that "so far no videos were used in the crash investigation." He added, "A' " person who has such a video needs to immediately give it to the investigators.\" Robin's comments" " follow claims by two magazines, German daily Bild and French Paris Match, of a cell phone video" " showing the harrowing final seconds from on board Germanwings Flight 9525 as it crashed into the" " French Alps. All 150 on board were killed. Paris Match and Bild reported that the video was" " recovered from a phone at the wreckage site. The two publications described the supposed video, but" " did not post it on their websites. The publications said that they watched the video, which was" " found by a source close to the investigation. \"One can hear cries of 'My God' in several" ' languages," Paris Match reported. "Metallic banging can also be heard more than three times, perhaps' " of the pilot trying to open the cockpit door with a heavy object. Towards the end, after a heavy" ' shake, stronger than the others, the screaming intensifies. Then nothing." "It is a very disturbing' " scene,\" said Julian Reichelt, editor-in-chief of Bild online. An official with France's accident" " investigation agency, the BEA, said the agency is not aware of any such video. Lt. Col. Jean-Marc" " Menichini, a French Gendarmerie spokesman in charge of communications on rescue efforts around the" ' Germanwings crash site, told CNN that the reports were "completely wrong" and "unwarranted." Cell' ' phones have been collected at the site, he said, but that they "hadn\'t been exploited yet."' " Menichini said he believed the cell phones would need to be sent to the Criminal Research Institute" " in Rosny sous-Bois, near Paris, in order to be analyzed by specialized technicians working" " hand-in-hand with investigators. But none of the cell phones found so far have been sent to the" " institute, Menichini said. Asked whether staff involved in the search could have leaked a memory" ' card to the media, Menichini answered with a categorical "no." Reichelt told "Erin Burnett:' ' Outfront" that he had watched the video and stood by the report, saying Bild and Paris Match are' ' "very confident" that the clip is real. He noted that investigators only revealed they\'d recovered' ' cell phones from the crash site after Bild and Paris Match published their reports. "That is' " something we did not know before. ... Overall we can say many things of the investigation weren't" ' revealed by the investigation at the beginning," he said. What was mental state of Germanwings' " co-pilot? German airline Lufthansa confirmed Tuesday that co-pilot Andreas Lubitz had battled" " depression years before he took the controls of Germanwings Flight 9525, which he's accused of" " deliberately crashing last week in the French Alps. Lubitz told his Lufthansa flight training school" ' in 2009 that he had a "previous episode of severe depression," the airline said Tuesday. Email' " correspondence between Lubitz and the school discovered in an internal investigation, Lufthansa" " said, included medical documents he submitted in connection with resuming his flight training. The" " announcement indicates that Lufthansa, the parent company of Germanwings, knew of Lubitz's battle" " with depression, allowed him to continue training and ultimately put him in the cockpit. Lufthansa," " whose CEO Carsten Spohr previously said Lubitz was 100% fit to fly, described its statement Tuesday" ' as a "swift and seamless clarification" and said it was sharing the information and documents --' " including training and medical records -- with public prosecutors. Spohr traveled to the crash site" " Wednesday, where recovery teams have been working for the past week to recover human remains and" " plane debris scattered across a steep mountainside. He saw the crisis center set up in" " Seyne-les-Alpes, laid a wreath in the village of Le Vernet, closer to the crash site, where grieving" " families have left flowers at a simple stone memorial. Menichini told CNN late Tuesday that no" " visible human remains were left at the site but recovery teams would keep searching. French" " President Francois Hollande, speaking Tuesday, said that it should be possible to identify all the" " victims using DNA analysis by the end of the week, sooner than authorities had previously suggested." " In the meantime, the recovery of the victims' personal belongings will start Wednesday, Menichini" " said. Among those personal belongings could be more cell phones belonging to the 144 passengers and" " six crew on board. Check out the latest from our correspondents . The details about Lubitz's" " correspondence with the flight school during his training were among several developments as" " investigators continued to delve into what caused the crash and Lubitz's possible motive for" " downing the jet. A Lufthansa spokesperson told CNN on Tuesday that Lubitz had a valid medical" ' certificate, had passed all his examinations and "held all the licenses required." Earlier, a' " spokesman for the prosecutor's office in Dusseldorf, Christoph Kumpa, said medical records reveal" " Lubitz suffered from suicidal tendencies at some point before his aviation career and underwent" " psychotherapy before he got his pilot's license. Kumpa emphasized there's no evidence suggesting" " Lubitz was suicidal or acting aggressively before the crash. Investigators are looking into whether" " Lubitz feared his medical condition would cause him to lose his pilot's license, a European" ' government official briefed on the investigation told CNN on Tuesday. While flying was "a big part' " of his life,\" the source said, it's only one theory being considered. Another source, a law" " enforcement official briefed on the investigation, also told CNN that authorities believe the" " primary motive for Lubitz to bring down the plane was that he feared he would not be allowed to fly" " because of his medical problems. Lubitz's girlfriend told investigators he had seen an eye doctor" " and a neuropsychologist, both of whom deemed him unfit to work recently and concluded he had" " psychological issues, the European government official said. But no matter what details emerge about" " his previous mental health struggles, there's more to the story, said Brian Russell, a forensic" ' psychologist. "Psychology can explain why somebody would turn rage inward on themselves about the' " fact that maybe they weren't going to keep doing their job and they're upset about that and so" ' they\'re suicidal," he said. "But there is no mental illness that explains why somebody then feels' " entitled to also take that rage and turn it outward on 149 other people who had nothing to do with" " the person's problems.\" Germanwings crash compensation: What we know .
