Pro-Russian rebels denied being behind the attack.He is set to meet Mr Putin at the G20 meeting in Brisbane in November.The prime minister told reporters on Monday: "Look, I'm going to shirtfront Mr Putin ... you bet I am."Shirtfronting is an Australian football term which means aggressively charging and knocking down one's opponent."I am going to be saying to Mr Putin [that] Australians were murdered. They were murdered by Russian-backed rebels using Russian-supplied equipment," he said in remarks quoted by the Australian Broadcasting Corporation.Mr Putin has denied Russia had any involvement in the incident. Mr Abbott has faced criticism at home for allowing Mr Putin to attend the summit.Opposition leader Bill Shorten said Mr Putin's presence amounted to "rubbing our faces" in the aftermath of MH17, reported Fairfax Media.But on Sunday Mr Abbott said it was not in Australia's power to ban Mr Putin as it would go against the consensus of G20 members.Fairfax reported Mr Abbott as saying he would be seeking assurance from Mr Putin that "justice is done".Mr Abbott's latest comments come as the English version of Russian newspaper Pravda published an opinion piece attacking him for recent strongly-worded remarks about Russia.The piece said Mr Abbott was "insolent" and Australia had a "colonial chip on its shoulder".(BBC)Bakudaily.Az
