Melbourne - A Sri Lankan student who tried to enter an airline cockpit with what he said was a bomb before terrified passengers overpowered him, had been released from psychiatric care just before boarding the plane, Australian police said Thursday.

Shrapnel from a Buk missile was found in the bodies of victims from the Malaysia Airlines flight MH17 crash, according to a Ukrainian investigator that was formerly part of the international team researching the cause of the disaster.
