Outrage as Indian student killed in Australia

"I obviously unreservedly condemn this attack," Julia Gillard, the Australian deputy prime minister, told reporters on Monday.

"This is a nation that welcomes international students. We want to make them welcome, this is a welcoming and accepting country," he said.

Garg, 21, was a graduate accounting student at an Australian university.

His killing is the latest in a series of attacks on Indian students in the country.

Police said the motive for the attack, which they described as "vicious", was not known.

Media in India have labelled the series of attacks against Indian students in Australia as racist, but police and the Australian government have said the attacks are criminal, not racist.

SM Krishna, the Indian external affairs minister issued a statement on Sunday, condemning the "brutal attack", with Indian media warning the attacks were creating "deep anger" in India and could have a "bearing on bilateral ties".
