"At around 1345 hours, troops guarding the borderline observed suspicious movements at Keri sector in Rajouri," PRO Defence S N Acharya said.
Immediately the entire area was cordoned off by the troops as the terrorist fired indiscriminately at the Indian post, he said.
Fifteen minutes later, Pakistani troops violated the ceasefire and fired at the forward Indian post to give cover fire to the infiltrating militant, the PRO said.
At around 1500 hours, contact was established with the militant who opened fire and in the ensuing gunfight with the troops, he was killed, the PRO said.
