NEW DELHI (AP) — India said Thursday that Canada has informed it about the arrest of three Indian men who have been charged with the murder of a Sikh separatist leader Hardeep Singh Nijjar in British Columbia last year, but insisted that no relevant information or specific evidence about Delhi’s involvement has been shared by the Canadian authorities till date.

India’s External Affairs Ministry spokesman Randhir Jaiswal told reporters that the two countries were discussing the issue but accused Canada of providing shelter to those who are advocating violence against India.

He said that Delhi had complained to the Canadian authorities that the people associated with organized crime in India had been allowed entry and residency in Canada. ``Many of our extradition requests are pending.”

“Our diplomats have been threatened with impunity and obstructed in their performance of duties,” Jaiswal added. We are having discussions at the diplomatic level on all these matters,” he said.
