Protest by Khalistani supporters: India summons Canadian envoy

"The Government of India sought an explanation on how such elements were allowed, in the presence of police, to breach the security of our diplomatic Mission and Consulates," read a statement issued by the Ministry of External Affairs.

"The Government of Canada was reminded of its obligations under the Vienna Convention, and asked to arrest and prosecute the individuals who have already been identified as being involved in such acts," read the statement.

"It is expected that the Canadian Government will take all steps which are required to ensure the safety of our diplomats and security of our diplomatic premises so that they are able to fulfil their normal diplomatic functions," the statement said.

Suspected Khalistani supporters recently attacked Indian missions in the UK and the US following Punjab government's crackdown on Waris Punjab De and its chief Khalistan sympathiser Amritpal Singh.

Last Sunday, an event in Canada was cancelled due to security concerns after a violent protest by Khalistan supporters, reports NDTV.

The event had been organised at the Taj Park Convention Centre in Surrey to honour Sanjay Kumar Verma, the Indian envoy to Canada, while he was on his first visit to the west coast, the Indian news channel reported.
