1972 — India and Pakistan sign a peace accord, renaming the ceasefire line in Kashmir as the Line of Control, a heavily fortified stretch of military outposts that divide the region between them. Both sides deploy more troops along the frontier, turning it into a heavily fortified stretch of military outposts.

The ceasefire has halted what some analysts say was the most serious fighting between the two countries since a 1971 war. But India's recent suspension of a key water-sharing treaty remains in place.

Pakistan is accused of violating a cease-fire with India just hours after agreeing to halt hostilities on Saturday.
