NEW DELHI : The Pakistan High Commission has rejected the visa of 150 Sikh pilgrims visiting Pakistan to commemorate the martyrdom day of 5th Sikh Guru Arjan Dev. The visa was rejected after differences over the date of observing the martyrdom day, with SGPC officials wanting the visa for Sikh pilgrims for May 22, while Pakistan said it would grant visa for June 16 when Pakistan Sikh Gurdwara Prabandhak Committee observes the anniversary, reported PTI on Friday.
