In January 2013, India denounced Pakistan over a fire-fight in the disputed territory of Kashmir in which two Indian soldiers were killed, but the nuclear-armed rivals both appeared determined to prevent the clash escalating into a full diplomatic crisis.
The body of one of the soldiers was found "badly mutilated" in a forested area on the side controlled by India.
Firing and small skirmishes between the two countries are common along the 740-km (460-mile) LoC despite a ceasefire and slowly improving bilateral ties.
There were more than 75 ceasefire violations along the Line of Control in 2012, killing eight people. Most of the violations were exchanges of fire between the two sides.
Thousands of weary people living in villages near the military control line fear they will again be caught in the crossfire after the recent border clashes.
India and Pakistan have fought three wars since 1947, when they became independent from Britain. The two countries share many similarities in language and culture, though most of Pakistan's citizens are Muslim and most of India's Hindu.
Kashmir, and the human rights abuses committed there by Indian troops, is a politically explosive issue in Pakistan. Pakistani security forces have long trained militant groups to attack Indian soldiers.
