At least three alleged terrorists were killed and four security personnel injured during intelligence-based operations in Peshawar, police and military said.

A gunfight took place Saturday morning in the Chamkani area of Peshawar when terrorists attacked a police party conducting an intelligence-based operation.

The terrorists were holed up in an abandoned building previously used as a floor mill, police officials said.

Officials told DawnNews that the operation continued for three hours and was launched on a tip off on the presence of terrorists in the area.

A large number of army personnel subsequently reached at the site to support the policemen under attack.

Three policemen, which included two station house officers, and one soldier received injuries during the operation.

A suspected facilitator of the terrorists was arrested, officials said, adding that some arrests were also made inside the building.

Capital City Police Officer (CCPO), Peshawar Tahir Khan said that weapons, explosive material, detonators, footage and documents were recovered from the building during the search operation.

The owner of the abandoned building will soon be interrogated, the CCPO said.

He further said that the injured personnel were out of danger.

Inspector General of Police Salahuddin dubbed the development a major achievement for the Peshawar police. He said that the terrorists were part of an organised network and responsible for a recent attack on a police party and target killings in the area.

"A high profile terrorist commander was also among those killed," the IGP said.
