Indian and Pakistani troops have exchanged fire for the fourth day in a row in disputed Kashmir, New Delhi's military said on April 28.
There are no reports of casualties and Islamabad has yet to confirm the exchange of fire.
India has accused Pakistan of supporting "cross-border terrorism" after a gunman killed 26 people last week in the worst attack on civilians in Muslim-majority Kashmir in a quarter of a century.
This attack has increased tensions between the two nuclear-powered rivals.
Islamabad has denied any role, saying it was an attempt to link Pakistan to the attack and vowing to respond to India's actions.
"During the night between April 27 and 28... Pakistani army posts opened unprovoked fire across the Line of Control," the Indian army said, referring to the de facto border in disputed Kashmir.
"Indian troops responded promptly and effectively," the statement said.
After the April 22 attack, New Delhi took several diplomatic steps, withdrawing visas for Pakistanis, suspending a water-sharing agreement and announcing the closure of the main land border with Pakistan.
In response, Islamabad ordered the expulsion of Indian diplomats and military advisers, canceled visas for Indian citizens, and banned Indian aircraft from using Pakistani airspace.
The United Nations has called on the parties to exercise "maximum restraint" so that issues "can be resolved peacefully through mutual and constructive engagement." (A2 Televizion)
