Amritsar, May 9 -- Following escalating border tensions between India and Pakistan after the Pahalgam terror attack on April 22, India has closed its side of the Kartarpur Corridor - the only active surface-level link between the two countries - indefinitely. The Union ministry of home affairs' bureau of immigration announced the closure of the corridor "till further orders". The closure has halted the pilgrimage of Indian Sikh devotees to the historic Gurdwara Darbar Sahib in Kartarpur, Narowal district, Pakistan, while Pakistan continues to keep the corridor open on its side. The 4.7-km passage connects Dera Baba Nanak Sahib in India's Gurdaspur and Gurdwara Darbar Sahib in Pakistan's Kartarpur, believed to be the final resting place of Guru Nanak Dev. On Wednesday morning, around 150 Sikh pilgrims who had arrived at the Dera Baba Nanak integrated check post in Gurdaspur district wereturned back after waiting for over 90 minutes. In contrast, Pakistan has maintained that the Kartarpur Corridor remains open on its end. Ramesh Singh Arora, president of the Pakistan Sikh Gurdwara Parbandhak Committee (PSGPC) and a former MLA, appointed as ambassador for the corridor, said, "The corridor is open from our side. It is a conscious decision of our government to continue welcoming the pilgrims." He added that the corridor was a symbol of peace, brotherhood and harmony propagated by Guru Nanak Dev. "On Tuesday, we received about 200 pilgrims from India and suddenly, the next day, the arrival was zero. When we checked, we were told thatIndia had stopped pilgrims from going to Kartarpur Corridor. Despite the corridor's close down from India's side, the Pakistan government has decided to keep it open as a goodwill gesture," Arora told HT overWhatsApp. He added that PSGPC had also started the process for facilitating pilgrimage visas to Indian pilgrims for June to mark the martyrdom of Guru Arjan Dev....
