( CNN ) -- Tensions between India and Pakistan flared Sunday in the Kashmir region , with at least one Pakistani soldier killed in the violence , its military said . But exactly what happened depends on the source . According to the Pakistani military , Indian troops crossed the Line of Control -- the de facto border between India and Pakistan in the disputed Kashmir region -- and attacked a military post . `` Pakistan Army troops effectively responded and repulsed the attack successfully , '' but one Pakistani soldier was killed and another critically injured , the military said . The Indian Defense Ministry , however , said Pakistani troops opened fire unprovoked on Indian posts in the north Uri sector of Indian-administered Kashmir . Indian troops retaliated and forced Pakistani troops to stop firing , the defense ministry said . The ministry did not immediately report the number of casualties , but said three civilians were killed by Pakistani shelling in the area last October . The territory under dispute lies in India 's Kashmir Valley , separated from Pakistan by the 450-mile Line of Control . The two south Asian nuclear neighbors have had a bilateral ceasefire along the de facto border since November 2003 . But the ceasefire has been violated repeatedly , with both sides accusing each other of offenses . Bilateral talks were temporarily suspended in 2008 following an attack by Pakistani militants in Mumbai , India 's most populous city . The negotiations resumed last year . The conflict dates back to 1947 after Britain relinquished control of the Indian subcontinent , giving birth to India and Pakistan .
