Australian Prime Minister Kevin Rudd, who is on a visit to India, on Thursday discussed with Prime Minister Manmohan Singh the attacks on Indian nationals in his country.

Rudd assured the Prime Minister that his government was committed to stopping the attacks on Indian nationals in his country but authorities could not totally rule out such incidents in future.

Rudd said, "As Australian PM, I am deeply disturbed and disgusted at the violence against any foreign students studying in Australia and who are in our country as our guests. Such attacks will not be tolerated. They will be dealt with full force of Australia's criminal justice system."

"But I can't say to you... since we are dealing with such large numbers... half a million foreign students in Australia at any given time, that you can rule out the possibility of future incidents," he added.

Manmohan had conveyed to his counterpart India's concern over safety and security of Indian students there.
