SYDNEY (AP) — Australian Prime Minister Tony Abbott is calling for an independent, international investigation into the downing of a Malaysian jetliner in Ukraine and demanding Russia’s cooperation.

Abbott on Saturday repeated his assertion that all evidence suggests that the missile that shot down Malaysia Airlines Flight 17 came from an area controlled by Russian-backed separatists, using equipment likely supplied by Russia.

Abbott said Australia takes “a very dim view of countries that facilitate the killing of Australians.”

He warned that any party that tries to block access to or contaminate the crash site is “no friend of justice” and “no friend of peace.”

Thursday’s crash killed all 298 aboard, including 28 Australians.
