The Malaysia Airlines Flight MH17 crash that killed 298 people in July last year was caused by a Buk missile system, the Dutch Safety Board concluded in one of its final reports on Tuesday.

The long-awaited findings of the board, which was not empowered to address questions of responsibility, did not specify who launched the missile.

But Dutch Prime Minister Mark Rutte called on Russia to cooperate fully with the criminal investigation into who was responsible for the downing.
