Unidentified gunmen killed two Pakistani paramilitary soldiers in the troubled Baluchistan province, where tribal militants are battling for autonomy, a senior police official said on Saturday. Four men riding on a motorcycle opened fire on the soldiers of the Frontier Constabulary on Friday evening in Khuzdar town, 290 km (180 miles) southeast of the provincial capital Quetta, said Rahmatullah Sasoli, a senior police official. Both the soldiers died on the spot, he was quoted as saying by Reuters.
