A Dutch judicial statement said today the international investigating team is looking for witnesses "that can tell more about the transport, crew and firing of a Buk missile system in the Donbass region."
The cause of the MH17 disaster last summer is a subject of major diplomatic disputes. Ukraine and Western governments say Russia-backed separatist fighters are responsible for downing the plane, while Russian state-run television has claimed Ukraine's air force was to blame. All 298 people aboard the Boeing 777 flying from Amsterdam to Kuala Lumpur were killed.
