Army claims 20 killed in air strikes in North Waziristan region as part of anti-Taliban offensive near Afghan border.
An air force camp near the Pakistan city of Peshawar has come under attack by between seven and 10 fighters, a military spokesman has said.
Sources said the attack centred on a residential area of Badaber camp where high ranking officers were stationed who were probably the target of the assault.
Six fighters and two security personnel were reported to have been killed in the fighting.
A heavy contingent of the Quick Reaction Force has reached the spot and exchanges of fire with the fighters are ongoing.
“As per initial information, seven to 10 terrorists tried to break deep in the base” but troops managed to contain them, military spokeman Major General Asim Bajwa said in a tweet.
The area has been sealed by security forces.
Peshawar suffered the worst attack in Pakistani history in December when Taliban gunmen killed more than 150 people at an army-run school, most of them children.
