Two paramilitary soldiers were killed and four wounded in a landmine explosion in insurgency-hit southwest Pakistan on Saturday, an official said. The soldiers were patrolling a gas field in the town of Dera Bugti in gas-rich Baluchistan province on the border with Afghanistan and Iran when a landmine planted on a roadside exploded under their vehicle. "Two soldiers were killed and four others wounded in the incident," a spokesman for the paramilitary Frontier Corps told a foreign news agency. A spokesman for the Baluch Republican Army, Sarbaz Khan, later claimed responsibility of the attack. Hundreds of people have died in violence in the province since the insurgency flared in late 2004, with rebels demanding political autonomy and a greater share of profits from the region's natural resources.
