All Germanwings crash victims' remains have been identified and sent back to their families.

One hundred and fifty people died in the crash on 24 March after co-pilot Andreas Lubitz seized control of flight 4U9525 and deliberately flew it into the French Alps.

Marseille prosecutor Brice Robin said in a statement on 19 May that "the 150 death certificates have been signed, as well as the permits for burial".

Everyone on board the Airbus A320 perished after Lubitz locked the plane's pilot out of the cockpit and took over the aircraft.

It had taken off from Barcelona Airport at 9.01am for Duesseldorf but after climbing to 38,000ft, it slowly descended before plummeting at 700km (430mph) an hour into the mountain range at 9.40am.

It later emerged Lubitz, who had flown a total of 630 hours before the crash, had suffered from psychiatric problems in years before the disaster.

He also reportedly practised descending an outbound flight from Dusseldorf to Barcelona on the same day he led the passengers and flight crew to their deaths, a report claimed.
