Incendiary rhetoric on Sikh's murder stokes debate in Canada diaspora

A row between Canada and India over the murder of a Sikh separatist has stoked talk of political friction among some Sikhs and Hindus in the diaspora, though others say it's overblown.

After Mr Trudeau's public accusation on Monday that India may have been behind the killing of Hardeep Singh Nijjar on Canadian soil, a clip surfaced on social media showing the head of a US-based Sikh separatist group calling for Hindu Canadians to return to India.

"Indo-Canadian Hindus, you have repudiated your allegiance to Canada and the Canadian constitution," said Gurpatwant Singh Pannun, head of Sikhs for Justice, in a video that was reportedly filmed on 12 September.

"Your destination is India. Leave Canada. Go to India," he said.
