India suspended its participation in the Indus Waters Treaty with Pakistan last month after the killing of 26 civilians in Kashmir, which New Delhi blames on Islamabad. Pakistan denies the charges, which led to the worst fighting between the countries in decades before a ceasefire was agreed last week.

In January 1949, the first war between India and Pakistan over Kashmir concluded after the United Nations intervened to broker a cease-fire. Under the terms of the cease-fire, a line was drawn dividing the territory. India would occupy about two-thirds of the area, and Pakistan the other third.
