Jammu, Feb 10 (IANS): Indian and Pakistani troops Tuesday exchanged fire in a bid to stop bunker fortification on either side of the international border in Jammu district.

"At 11.57 p.m. today Pakistan Rangers fired 22 rounds of small arms from their Thathi border outpost towards Nawa Pind outpost of the BSF in R. S. Pura Sector while BSF troopers were working with an earth moving machine," a senior police officer told IANS in winter capital Jammu Tuesday.

"The work was stopped by our troops who retaliated by firing 11 rounds of small arms."
