The Pakistani army said on Tuesday its troops killed at least seven Islamic militants and injured several others in the troubled Bajaur tribal district that borders Afghanistan, reported dpa.
"Militants' fortified positions and hide outs around the Loi Sam area were today engaged in heavy fire," military spokesman Major Murad Khan told Deutsche Presse-Agentur dpa.
Three explosive-laden vehicles were also destroyed by the security forces in Kat Kot area, he added.
Clashes erupted in Bajaur early August when scores of pro-Taliban militants attacked a security checkpoint on a strategic hilltop in Loi Sam along the route used to transport supplies to insurgents in Afghanistan.
Military, backed by tanks and helicopter gunships, launched a massive operation to eliminate militants' hideouts. Bombing raids and heavy artillery fire have so far killed hundreds of insurgents, including some hardcore operatives of the al-Qaeda terrorist network.
