The armies of India and Pakistan once again exchanged heavy fire and artillery shells on line-of-control (LoC) in Kashmir region, officials said Wednesday.

The ceasefire violation took place Tuesday evening along the LoC in Krishna Ghati and Mendhar sectors of frontier Poonch district, around 185 km southwest of Srinagar city, the summer capital of Indian-controlled Kashmir.

"Pakistani troops last evening again resorted to unprovoked firing using machine guns and mortars on our several posts," said Col. R K Palta, Indian army spokesman based in Jammu. "However, we have not suffered any damage because of the firing."

LoC is a de facto border that divides Kashmir into Indian and Pakistani controlled parts.

Indian army officials say Pakistan has resorted to five ceasefire violations on LoC since Monday's Brigade -level flag meeting between the two armies on LoC at Chakan Da Bagh in Poonch. Reports said Indian army has also retaliated to the firing from Pakistani side.

However, Pakistan Tuesday night claimed firing from Indian side has killed its trooper on LoC.

The ongoing skirmish since January 2 between Indian and Pakistani troopers on LoC is heightening tension between the nuclear neighbors. Since then five troopers of both the countries (two from India and three from Pakistan) were killed in these skirmishes on LoC.

New Delhi and Islamabad in 2003 agreed to observe a ceasefire along the international border and LoC in Kashmir. Though some violations have been reported on both sides, the ceasefire remains in effect.

Kashmir, the Himalayan region divided between India and Pakistan, is claimed by both in full. Since their independence from British, the two countries have fought three wars, two exclusively over Kashmir.

Pakistan said it wants a third party inquiry into the ceasefire violations on the LoC. But New Delhi has out rightly rejected any UN investigation, saying they do not want to internationalize the issue.
