Australian Prime Minister Kevin Rudd today said the recent attacks on Indian youths were regrettable. However, he insisted that the assaults should be seen in the context of broader incidences of violence against locals and students of other ethnic groups. He said, obviously these are difficult matters for both India, and Australia. Nearly 100 cases of attacks on Indians, mostly students, were reported in Australia in 2009 as against 17 incidents of assaults in 2008.
