Germanwings crash: All victims identified

All the human remains found at the scene of the Germanwings air crash have been identified and will be returned to their families, a French prosecutor says.

The plane crashed in the French Alps on March 24 with 150 people on board.

Investigators say co-pilot Andreas Lubitz deliberately crashed the plane after locking the pilot out of the cockpit.

Experts have spent six weeks conducting DNA tests on the remains.

"The 150 death certificates can now be signed, as well as the 150 burial permits," said Brice Robin, Marseille's city prosecutor.

The victims were from 18 countries, including Australia, Argentina and Japan, but most of those on board were either Spanish or German.

Robin had previously said it was Lubitz's "intention to destroy [the] plane", which was flying from Barcelona to Duesseldorf.

Among the victims was a group of 16 students, 14 girls and two boys, and two of their teachers, from Joseph-Koenig school in Haltern, western Germany. They were travelling back from a Spanish exchange programme on the Germanwings flight.
