Sydney protesters will call on the Australian government to ban Russian President Vladimir Putin from this year’s G20 summit.

Sydney protesters will demand Russian President Vladimir Putin be banned from Australia after a devastating missile attack on Malaysia Airlines flight MH17 left 298 people dead, including 28 Australians.

A tough-talking Prime Minister Tony Abbott squarely pointed blame at Russia for the attack but wouldn’t say if Mr Putin was welcome to attend a G20 leaders summit in Brisbane in November.

While it was an important international gathering, Australia had to maintain its strength and self-respect, he said.

Two separate anti-Putin protests are organised for Saturday.

The Ukrainian-Australian community will hold a prayer vigil and protest at 9.15am in Lidcombe, in Sydney’s west, while a `Ban Putin from G20′ rally will be held at 2pm in the CBD.

The head of Australia’s Ukrainian community has accused Mr Putin of having “Australian blood on his hands”.
