India has summoned Canadian High Commissioner Cameron MacKay and conveyed its strong concerns about the actions by pro-Khalistani extremist elements against its diplomatic missions in Canada recently.

MacKay was summoned by the External Affairs Ministry on Saturday and sought an explanation on how “separatist and extremist elements” were allowed to breach the security of its diplomatic mission and consulates despite the presence of police, the Ministry of External Affairs said in a statement.

On Sunday last, India's High Commissioner to Canada Sanjay Kumar Verma was forced to skip an event in British Columbia province after a violent protest by Khalistan supporters.

Indian-origin journalist Sameer Kaushal, who was at the venue to cover the protest, was also assaulted by protesters.

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, the ministry said.

It said it expected the Canadian government to take all steps needed to ensure security of its diplomatic premises and the safety of its diplomats so that they are able to fulfil their normal diplomatic functions.

Canada has seen a rise in anti-India activities recently by Khalistan supporters who have vandalised some Hindu temples.

Earlier this month, pro-Khalistan supporters had attacked the Indian High Commission in London and vandalised the Indian consulate in San Francisco.

The External Affairs Ministry had summoned the Charge d'affaires of Britain and the US to voice strong protests against the developments at its missions.
