Pakistan suicide bomber kills six

A suspected suicide bomber has killed six people outside Pakistan's main air force maintenance facility.

Police said the attack took place near the Kamra aeronautical complex, 60km (35 miles) from the capital, Islamabad.

The bomber blew himself up when he was stopped at a checkpoint outside the complex. Among the dead were two security officials.

The attack comes as the Pakistani army continues its drive against Taliban bases in South Waziristan.

A wave of attacks on Pakistani cities has killed nearly 180 people during the month of October alone.

"It was a suicide attack, which killed six people, including four civilians and two Pakistan air force personnel," news agency AFP quoted district police chief Fakhar Sultan as saying.

"We have found a mutilated face, as well as other body parts, including legs and arms of the bomber," he said.

Nine people have also been wounded in the attack.

The attacks come as Pakistan is on high alert, following weeks of suicide attacks by militants.

Friday's attack is the third violent incident in and around Islamabad since Tuesday.

On Thursday, a Pakistani army brigadier and his driver were killed in a shooting incident in Islamabad.

On Tuesday, at least nine people died, two of them suicide bombers, and at least 18 were wounded in twin blasts at the International Islamic University.
