Toronto: A few hundred members of the Sikh community in Canada protested the unsolved murder of one of their leaders last month in the Vancouver area on Saturday outside the Indian consulate in Toronto. They claimed that Hardeep Singh Nijjar, the president of a Sikh temple and a supporter of the establishment of an independent Sikh state they hope to call Khalistan, was murdered by the Indian government. "When an Indian agency and system commit a crime, they have to be held accountable," said Kuljeet Singh, a representative of Sikhs for Justice, the US-based group that organised the demonstration.

The Royal Canadian Mounted Police (RCMP), according to another protester and lawyer Hakirt Singh, "should investigate this murder" as a political assassination. "You see tweets and responses from politicians when there is vandalism against a member of Parliament. Here, a Canadian citizen was murdered on Canadian soil. That is foreign meddling.

Nijjar was accused by India of carrying out terrorist attacks there, a claim he vigorously denied. "Khalistan! Khalistan!" was yelled by the demonstrators, who were almost exclusively male and carried yellow flags with blue logos to represent their separatist movement. They travelled from the Toronto suburbs to the Indian consulate, where they were met by about 50 diaspora citizens who were in favour of the Indian government. There is a poster here urging the murder of Indian diplomats. We are worried because these groups have previously carried out terrorist acts and because politicians are doing nothing, according to Vijay Jain, an IT consultant who was a member of the counterdemonstrators, who spoke to AFP. One Sikh protester was arrested after breaking down a barrier and running to the other side as a queue of 20 police officers intervened to separate the two groups. Intensities between Canada and India have increased as a result of the murder of the Sikh leader.

Arindam Bagchi, a spokesman for the Indian foreign minister, stated on Thursday that "we have asked the Canadian government to take all necessary measures to ensure the safety of our diplomats." The majority of Sikhs outside of their native Punjab, India, reside in Canada.
