Members of All India Human Rights Watch (AIHRW), a local social organisation, hold a placard and candles as they take part in a candlelight vigil to protest against the recent attacks on Indian students in Australia, in the northern Indian city of Chandigarh June 9, 2009. India's Prime Minister Manmohan Singh said on Tuesday he was "appalled" at the attacks on Indian students in Australia, some of which are "racist" in nature, and proposed to involve himself in a high-level engagement with that country on the issue, local media reported.
