Which two countries are connected by the Kartarpur Corridor?

The Kartarpur Corridor is a visa-free border crossing and secure corridor, connecting the Gurdwara Darbar Sahib in Pakistan to the border with India.

The crossing allows Sikh devotees from India to visit the gurdwara in Kartarpur, 4.7 kilometres (2.9 miles) from the India–Pakistan border without a visa, creating a link which allows pilgrims holding Indian passports to easily visit both the Kartarpur shrine and Gurdwara Dera Baba Nanak on the Indian side of the border. Pakistani Sikhs are unable to use the border crossing, and cannot access the Gurdwara Dera Baba Nanak without first obtaining an Indian visa.
