In the first ceasefire violation this year, Pakistani troops fired at Indian posts along the Line of Control in Jammu and Kashmir's Poonch district on Wednesday morning.
The Indian soldiers retaliated and the exchange of fire lasted for over an hour, a senior army officer said adding "there were no casualties on our side of the border".
Pakistani troops opened small arms fire on the Indian positions in Ghambir forward area at around 0600 hours after the army had earlier foiled an infiltration bid.
"It was a ceasefire violation as the firing came from Pakistani posts," the officer said.
A group of four to five militants, trying to sneak into India, fired at troops patrolling the Ghambir forward area in Bhimber Gali sub-sector late on Tuesday night, he said.
The troops fired back forcing them to flee to Pakistan, the officer said. In December last year, there were four truce violations by Pakistani troops along the border in Jammu and Kashmir
