By Anna Mehler Paperny TORONTO (Reuters) -Twice since July 2022, Moninder Singh, spokesperson for a Sikh advocacy group in Canada's British Columbia province, has had police come to his door in the Vancouver suburb of Surrey.

India’s government is denying that it works with mobsters to target Sikh separatists in Canada as alleged publicly this week by Canadian officials in an escalating diplomatic dispute.

The diplomatic rift has suddenly grown more stark as Canada amplifies its accusations that India is directing lethal operations abroad.
