International prosecutors investigating the downing of flight MH17 over eastern Ukraine in 2014 say the missile that hit the plane was fired from territory controlled by Russian-backed rebels, the BBC reports.
They said the missile launcher was brought into Ukraine from Russia.
All 298 people on board the Boeing 777 died when it broke apart in midair flying from Amsterdam to Kuala Lumpur.
The Dutch-led Joint Investigation Team (JIT) consists of prosecutors from the Netherlands, Australia, Belgium, Malaysia and Ukraine.
An inquiry by the Dutch Safety Board last year found that a Russian-made Buk missile hit the plane but did not say where it was fired from.
