NEW DELHI - India's minister of state for foreign affairs says her country is concerned about Sikh extremism in Canada. Preneet Kaur made the comments during a meeting with Prime Minister Stephen Harper at a downtown New Delhi hotel. Kaur says that her government is worried about the rise of anti-India rhetoric in Canada, particularly after taking great pains to stamp out unrest in the Punjab region. Harper responded by saying the vast majority of Canadians and Indo-Canadians support a united India. Pockets of support for a separate Indian state, called Khalistan, are active in Canada, particularly in British Columbia. Some Indo-Canadians criticize the Indian government for harassing Sikhs, and never bringing to justice the perpetrators of a massacre of more than 3,000 Sikhs in November 1984.
