India and Pakistan have fought three wars since independence, two of them over Kashmir, in 1947 and 1965. A third in 1971 led to the creation of Bangladesh. In 1999, the they clashed again in the Kargil region in what was described as an undeclared war. A U.N.-brokered ceasefire line, the Line of Control, now divides the region.

Twenty-six people were killed and 17 were injured when suspected militants opened fire at tourists in India's Jammu and Kashmir territory on Tuesday, the worst such attack in the country in nearly two decades.
