A lead investigator into the Germanwings crash has called for anyone with footage of the disaster to hand it over to the authorities.
French prosecutor Brice Robin said he was not aware of a video, reported by German and French media, showing the last seconds before the crash.
Bild and Paris Match said on Tuesday they had mobile phone footage from inside the plane.
Airline bosses spoke of their regret on a visit to the crash site on Wednesday.
Their statement comes amid mounting questions about how much the co-pilot Andreas Lubitz’s employers knew about his mental health after it emerged he had disclosed a previous bout of “severe depression”.
A recording from the cockpit of the aircraft suggests Lubitz, 27, deliberately caused the disaster, killing all 150 on board.
‘Sound of screaming’
Mr Robin said investigators were not yet examining mobile phones found at the crash site, and he was not aware of footage from phones having been recovered.
German newspaper Bild and French news magazine Paris Match said they had obtained a video which recorded the sound of passengers screaming and the sound of a metal object striking the cockpit door.
