KHAR: Three militants were killed and a security official was injured as Afghanistan-based militants attacked a checkpoint along the border in Nawagai tehsil of Bajaur tribal region on Tuesday.

An official said the militants entered the area from Afghanistan and fired several rockets and mortars at the checkpost in Matak, 40km from Khar. “Security forces pushed back the militants and at least three attackers were killed and one security personnel was injured during the exchange of fire,” the official said.

“We believe militants living in Afghanistan’s Kunar province are responsible for the attack,” the official said. Security forces deployed more troops at several posts along the border.

Meanwhile, militants fired a rocket at a checkpost of Levies Force in Khar on Monday night.

The checkpost was partially damaged, but no casualty was reported, according to officials.

The administration launched a search and arrested several tribesmen under the collective responsibility clause of the Frontier Crimes Regulations (FCR).

Officials said two security personnel were killed when a bomb detonated by remote control exploded Damadola village of Bajaur.

The personnel were on routine patrol in the area when the bomb went off. No-one has claimed responsibility for the attack.
