The Indian army on Wednesday said that three of its soldiers have been killed in cross border firing in held Kashmir, the latest skirmish between the nuclear-armed neighbours.

One Indian soldier died after coming under sniper fire on Wednesday in Machhal sector, army spokesman Colonel Rajesh Kalia told AFP. Indian soldiers retaliated by targeting the Pakistan army posts across the Line of Control.

The sniper attack came a day after two soldiers were killed in firing in Naushera sector, a separate Indian army statement said.

Three civilians on the Pakistani side of Kashmir were also martyred in that exchange of fire, according to local officials.

India blamed the September attack on Pakistan-based militants and responded with "surgical strikes" on what New Delhi described as terrorist launching pads across the dividing line.

Pakistan denied the strikes took place and the two sides have since expelled diplomats from their countries in a tit-for-tat row.

The border skirmishes come against the backdrop of months of protests against Indian rule of Kashmir, sparked by the martyrdom of Burhan Wani in July.

Nearly 90 people, most of them young protesters, have been martyred in clashes with security forces in occupied Kashmir since then.
