India on Monday said it had summoned Pakistan’s Deputy High Commissioner Syed Haider Shah to register its protest against posters referring to Khalistan reportedly being put up in gurudwaras that Sikh pilgrims from India are visiting.

The Ministry of External Affairs said India had asked Pakistan to “immediately stop all such activities that were aimed at undermining India’s sovereignty and territorial integrity”.

“Such repeated attempts by authorities and entities in Pakistan to extend support to secessionist movements in India amount to interference in the internal affairs of India,” the ministry said. “Moreover, such incidents during the visit of the Indian pilgrims went against the spirit of the bilateral Protocol of 1974 governing the exchange of visits of pilgrims between the two countries.”

The Ministry of External Affairs had claimed on Sunday that Pakistani authorities blocked Indian diplomats, including the high commissioner, from meeting Sikh pilgrims visiting the country on Baisakhi on Saturday. A group of around 1,800 pilgrims reached Pakistan on April 12 under a bilateral agreement on facilitating religious visits, the ministry said. However, Pakistan rejected the allegations as baseless.
