Gunmen and a suicide bomber have attacked a paramilitary force headquarters in Pakistan’s northwestern city of Peshawar, killing at least three security personnel, according to media reports.

The Dawn daily reported on Monday that the headquarters of the Federal Constabulary (FC) was “under attack” and that a suicide bomber had detonated their explosives at the gate to the complex.

The daily cited police and security sources in Peshawar.

It cited the sources as saying that three fighters and three FC officers were killed in the attack, and that security forces had cordoned off the area.

The Dunya News website, citing Peshawar Police Officer Mian Saeed, said the three slain FC officers had been stationed at the gate and were killed in the explosion there.

The Reuters news agency reported that the complex was hit by two suicide bombers and that at least three people had been killed.

“The first suicide bomber first carried out an attack on the main entrance of the constabulary, and the other one entered the compound,” a senior official who spoke on condition of anonymity was quoted as saying.

“Law enforcement personnel, including the army and police, have cordoned off the area and are carefully handling the situation as we suspect there are some terrorists inside the headquarters,” the official added.

The headquarters of the force is located in a crowded area, close to a military cantonment.

According to Dawn, the attacks also caused injuries to at least six civilians, who were take to the Lady Reading Hospital in Peshawar.

A spokesman for the hospital told Dawn that all those wounded were in stable condition.

The daily also reported that an emergency has been declared at the hospital as well as at Khyber Teaching Hospital.
