Peshawar: Pakistani Taliban militants attacked an air force base in the country’s restive northwest Friday, killing at least 17 people in their deadliest high-profile assault in months following a major military offensive against them.

The army said that the group of insurgents launched the assault at dawn at the residential compound near Peshawar, the gateway to tribal regions on the Afghan border that have long been a haven for militants.

Soldiers quickly surrounded the attackers, confining them to a small area and killing at least 13 of them, according to the military’s main spokesman Major General Asim Bajwa.

But he said in a tweet that a group of militants attacked a mosque within the camp compound and killed 16 people offering dawn prayers. Separately an army captain was killed in fighting with the insurgents, he said.

The Tehreek-e-Taliban Pakistan (TTP) group claimed responsibility in an e-mail sent to journalists, saying their ‘suicide unit’ carried out the attack.

The attack on the Badaber base, 10 kilometres (six miles) south of Peshawar, triggered fierce gunbattles between insurgents and the military in which at least 10 soldiers were wounded.

Bajwa said operations were continuing to flush out any remaining gunmen and hailed the defenders’ reaction to the attack.

He said Peshawar’s Brigade Commander led the operation along with specialist ‘quick response’ forces, army commandos and air force personnel.

Photos tweeted by Bajwa showed what appeared to be seven heavily armed militants lying dead, several of them in pools of blood.

Sabitullah Khan, a labourer who lives nearby, said a wall of his house collapsed under the force of grenade blasts during the attack.

‘It was horrifying to hear the blasts and intense firing,’ he said.

Kifayatullah, who runs a grocery store near the camp, told AFP he was praying at a mosque outside the compound when the began with ‘a grenade explosion and intense gunfire’.

‘It was next to impossible to come out of the mosque. We jumped from the window of the mosque and escaped,’ he said.

A senior PAF official told AFP the facility attacked on Friday was a residential camp for air force personnel.

‘There are no air assets including combat aircraft deployed at the base,’ he said, requesting anonymity.

Taliban still determined

The tribal badlands that lie just a short drive from Peshawar have been the scene of a major military offensive against Taliban and other militants over the past year.

The army launched the ‘Zarb-e-Azb’ operation in June 2014 in a bid to wipe out militant bases in North Waziristan tribal area and so bring an end to the bloody decade-long Islamist insurgency that has cost Pakistan thousands of lives.

Peshawar suffered the worst terror attack in Pakistani history in December when Taliban gunmen stormed an army-run school and massacred more than 150 people, most of them children.

The army intensified its offensive after the school attack and since then there has been something of a lull in violence. The last major attack in the city came in February when three heavily armed Taliban militants stormed a Shiite mosque, killing 21 people.

While the military offensive appears to have disrupted the TTP’s network, Friday’s attack shows they are still determined to carry on their fight against the state with audacious attacks on high-profile targets.

A TTP faction last month claimed responsibility for a double suicide bombing that killed the home minister of Punjab province along with 15 other people.
