Indian troops resorted to "unprovoked firing" along the Working Boundary on Monday, said a statement issued by Inter-Services Public Relations (ISPR), the military’s public relations wing.

According to the ISPR statement, the firing took place in Zafarwal sector near the boundary at 8:30am.

Pakistan Rangers Punjab responded to the firing from across the border effectively, it added.

The statement did not say whether there were any casualties on either side.

Last week, after a considerable silence, Indian troops had engaged in unprovoked shelling from across the Line of Control (LoC) in Azad Jammu and Kashmir's Khanjar sector. No casualties were reported during that incident.

Tense relations

Incidents of cross-border firing were reported with frequency in the last months of 2016 as tensions simmered between Pakistan and India over the Kashmir issue. Exchanges of fire have been reported sporadically since the new year began.

Following the Uri army base attack in September, Indian Prime Minister Narendra Modi stepped up a drive to isolate Pakistan diplomatically.

In the days following the attack, India claimed to have conducted a cross-border 'surgical strike' against 'launch pads of terror' in Azad Jammu and Kashmir — a claim Pakistan strongly rejected.

Pakistan maintains that India is attempting to divert the world's attention away from 'atrocities' committed by government forces in India-held Kashmir.

The two countries have locked horns over the Kashmir issue after Indian forces stepped up a crackdown against protesters after Hizbul Mujahideen commander Burhan Wani was killed by government forces in July.
