Indian and Pakistani forces exchanged fire on Tuesday in the disputed Himalayan region of Kashmir, Indian officials said, two days after a militant attack killed 18 soldiers in the area.
Indian officials said their military posts at the border town of Uri came under heavy fire from Pakistani forces shooting across the Line of Control, the military frontier which divides the disputed Kashmir region into two parts, one administered by India and the other by Pakistan.
"Our forces retaliated and the exchange of fire continued for about an hour," an army spokesman said.
India often accuses Pakistani forces of firing at Indian posts to give cover to militants attempting to sneak into Indian territory. The official said the attack was a violation of a 2003 ceasefire agreed between the neighbours.
On Sunday, four militants attacked the Indian army's base in Uri, killing 18 soldiers before they were shot dead.
The border skirmish comes as Delhi and Islamabad are locked in a war of words following the attack, which India blamed on Pakistan-based Jaish-e-Mohammad group.
Pakistan has denied the allegations as India claimed to have evidence to support its claims. The Indian army says it has recovered weapons and food with Pakistani markings during search operations following the attack.
