Pakistan has decided to allow fully-vaccinated Sikh pilgrims to visit Gurdwara Darbar Sahib, Kartarpur from next month with strict Covid-19 protocols, ahead of the 482nd death anniversary of Sikhism founder Guru Nanak Dev on September 22, media reports said on Sunday. On this occasion, three-day rituals will be held at the shrine from September 20. Guru Nanak died in Kartarpur on September 22, 1539. Pilgrimage to the Kartarpur Sahib gurdwara was suspended in March 2020 because of the Covid-19 outbreak. Due to the Delta variant, India was in category C in Pakistan from May 22 till August 12.
