Australian Prime Minister Tony Abbott said in an address to parliament that the aircraft was downed by a missile which seemed to have been launched by Russian-backed rebels. Julie Bishop, the Australian Minister for Foreign Affairs, said in an interview on Australian television that it was "extraordinary" that her Russian counterparts had refused to discuss the downing of MH17 when the Russian ambassador was summoned to meet her. The Russian government was critical of Abbott's response; Abbott was one of the first world leaders to publicly connect the shoot-down to Russia. Abbott later criticised the recovery efforts as "shambolic", and "more like a garden clean-up than a forensic investigation"; Bishop publicly warned separatist forces against treating the victims' bodies as hostages. Abbott also said in an interview on 13 October 2014, in anticipation of Russia's President Vladimir Putin's attendance at the 2014 G20 summit, scheduled for mid-November 2014 in Brisbane, Australia: "Australians were murdered. They were murdered by Russian-backed rebels using Russian-supplied equipment. We are very unhappy about this."
