A group of four armed persons from Pakistan occupied Kashmir (PoK) were seen moving towards an Indian forward post in Krishna Ghati sector in Poonch district around 0950 hours, PRO defence, S N Acharya, said.
Alert Indian troops took position and opened firing on the infiltrating persons, Acharya said, adding that they were pushed back towards PoK.
As the infiltration bid was foiled, Pakistani troops opened heavy firing on Indian posts in Mandi, Krishna Ghati and Chakan-Da-Bagh in Poonch sector.
Sher Shakti, PP1 and PP2 in Mandi sector, Kripan and Kranti posts in Krishna Ghati sector and Bahadur, Rekha and Neck posts in Poonch sector also came under firing, he said.
They fired small arms and 82 mm mortars on Indian posts and Indian troops also retaliated, resulting in exchanges.
The exchanges are on, he said, adding that there was no casualty or injury to any person on Indian side.
This is the third ceasefire violation in June this year and fifth in past nearly one month.
