Amritsar, May 8 -- Kartarpur Corridor, the only open surface link from India to Pakistan, was closed on Wednesday morning, hours after Operation Sindoor was launched. Nearly 150 Indian Sikh pilgrims, who had arrived to take the Kartarpur Corridor for the pilgrimage to the historic Sri Darbar Sahib gurdwara in Narowal district of Pakistan, were asked to return home after a wait of an hour and a half at the integrated check post on Wednesday morning. The ministry of home affairs' bureau of immigration announced the closure of the Kartarpur Corridor "till further orders". Gurdaspur deputy commissioner Dalwinderjit Singh, however, said that the corridor has been shut for Wednesday. He said the district administration had not received any orders from the government for the coming days. The pilgrims started arriving around 9am on Wednesday amid apprehensions that they would not be allowed to cross over to Pakistan due to the conflict underway since the wee hours. "Immigration and defence officials told us that the situation is not conducive and advised us to return around 11am. It's unfortunate that we could not make it but national interest is above all," said one of the pilgrims, requesting anonymity. After the escalating tension on the border since the Pahalgam terror attack on April 22, there has been a steady decline in the number of Indian Sikh pilgrims going to Pakistan....
