PESHAWAR: One soldier was killed and six others were injured Friday in a rocket attack on Kalaya, the agency headquarters of the restive northwestern Orakzai tribal region.

Official sources said that two rockets were fired on the Kalaya Headquarters as a result of which seven soldiers sustained injuries. One of the injured soldiers died on his way to a hospital, while six others are receiving medical treatment.

Last month, 18 suspected militants and six soldiers were killed during a gun-battle in Orakzai Agency. The gun-battle was set off by an attack by militants before dawn, on a check-post in Shireen Dara area of Lower Orakzai.

Orakzai is one of Pakistan’s seven semi-autonomous tribal regions in the northwest, where Pakistani Taliban and Al Qaeda-linked militants are said to have carved out strongholds.

It was a key abode of former Tehreek-i-Taliban Pakistan (TTP) chief Hakimullah Mehsud before he was killed in a US drone strike in North Waziristan in 2013.
