The Pakistan-India ceasefire line runs from the Karakoram Pass west-southwest to a point about 130 kilometres northwest of Lahore. This line, about 770 kilometres long, was arranged with United Nations (UNO) assistance at the end of the Indo-Pakistani War of 1947–48. The ceasefire line came into effect on 1 January 1949, after eighteen months of fighting between Indian forces and Pakistani forces and was last adjusted and agreed upon by the two countries according to the Shimla Agreement of 2 July 1972 between Indira Gandhi and Zulfikar Ali Bhutto.
