The Pakistan army opened heavy fire and shelled forward areas along the Line of Control (LoC) in five sectors in Jammu and Kashmir's Poonch district on Thursday, officials said.
The Indian Army retaliated befittingly, they said.
"The Pakistan army continued unprovoked ceasefire violation by firing with small arms and shelling with mortars along LoC in many locations," Jammu-based defence spokesperson Lt Col Devender Anand said.
"Around 0530, 1145 and 1215 hours today, the Pakistan army initiated unprovoked ceasefire violation by firing with small arms and intense shelling with mortars along the LoC in Mankote, Degwar and Mendhar sectors," he said.
In the evening, the Pakistan army targeted Balakote sector. Again around 2200 hours, it initiated ceasefire violation in Krishna Ghati sector in Poonch, he added.
The Indian Army retaliated befittingly, the spokesperson said.
The exchange of fire between the two sides was still on when last reports came in from the area.
On September 2, one junior commissioned officer of the Indian Army was killed in a ceasefire violation by Pakistan along the LoC in Keri sector of Rajouri.
