The final moments inside the doomed Germanwings plane which shows passengers screaming and crying have been revealed in a "chaotic" video recorded onboard.

In the clip found among the wreckage of the jet people can reportedly be heard crying "oh my God" and a large metallic banging noise happens three times.

The latter supports the theory that the captain, who had been locked out of the cockpit, tried to break down the door to stop co-pilot Andreas Lubitz.

Prosecutors investigating the crash which left 150 people dead said Lubitz, who had been suffering from depression, had "deliberately" destroyed the plane.

The video of the last few seconds inside the Germanwings plane was found on a mobile phone sim card among the debris from last Tuesday's crash in the French Alps.

The clip was recorded from the back of the Airbus A320 and was obtained tonight by French magazine Paris Match and German newspaper Bild.

Speaking about the video, the Parisian publication said: "One can hear cries of 'My God' in several languages. 

"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."

The video, which has yet to be made public, seems to suggest passengers were aware of what was happening and were terrified.

The Parisian magazine added that the clip: "Was so chaotic that it was hard to identify people, but the sounds of the screaming passengers made it perfectly clear that they were aware of what was about to happen to them."

Lufthansa said it was aware of reports about the footage but questioned whether a mobile phone could have withstood the impact.

A spokesman for the company said: "We have also read of reports in a French newspaper about the video.

"But we have not seen the video and we do not know if it exists. Therefore we cannot confirm if the video is genuine.

"Considering that everything on the plane was destroyed, it would be unusual for a mobile phone to survive the impact."

The news comes as it was claimed that Lubitz had told Lufthansa, owners of budget service Germanwings, of a "a serious depressive episode" six years ago.

Previously unseen e-mails between Lubitz and the German airline revealed he informed his flight school of mental health problems back in 2009.

It emerged last week that Lubitz had a sick note for the day of the crash declaring him unfit for work which was found torn up at his apartment.

Lubitz, who had recently split from his girlfriend, had been treated for suicidal tendencies years ago.

His former lover had told Bild that Lubitz had long plotted an event so horrific that he would go down in history.

He last year reportedly told the 26-year-old, known only as Mary W, that: "One day I will do something that will change the whole system, and then all will know my name and remember it."

Lubitz crashed the Germanwings plane with 144 passengers and six crew members into the French Alps last Tuesday March 24.

All onboard the plane, including three Britons and two babies, were killed.

It is believed that the captain of the plane Patrick Sonderheimer was locked out of the cockpit when he went to the toilet.

Sources have said Mr Sonderheimer tried to use an "onboard axe" to break through the door and regain controls of the plane.

The disaster happened on a flight between Barcelona and Dusseldorf.
