Islamabad, Pakistan CNN  — 

Militants in Pakistan killed two security forces and abducted 21 others in an assault on two military camps Thursday, a government official told CNN.

More than 200 people suspected to be members of the Taliban conducted the actions, said Nazeed Akbar, a government official.

The camps are nearly two miles apart on the outskirts of Peshawar. The militants swamped the camps on foot and in vehicles around 2 a.m.

A gunfight lasting more than an hour ensured. Along with those missing and killed, at least one security force member was injured.

The Pakistan Taliban confirmed they had the security forces in custody. The personnel belonged to a tribal police force engaged in fighting militants.

The northwestern region of Pakistan – near the volatile border with Afghanistan – has a large militant presence, and it has been plagued by fighting.

On Saturday, the Pakistani Taliban carried out a suicide bombing targeting a Khyber Pakhtunkhwa provincial official in downtown Peshawar, Bashir Bilour. The official was among 10 people killed; 17 other people were wounded.

Secretary-General Ban Ki-moon condemned the blast and issued his support for Pakistan “to combat the scourge of terrorism.”
