Pakistani army vehicle attacked

Two gunmen on a motorcycle have fired on a military vehicle in the Pakistani capital, Islamabad, police say.

There were no casualties in Tuesday morning's attack, according to police. The gunmen fled the scene.

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

It comes as the Pakistani army continues its drive against Taliban bases in South Waziristan, near the border with Afghanistan.

Last week a Pakistani army brigadier and his driver died in a shooting incident in Islamabad.

Senior police official Khan Khurshid Khan told Reuters news agency that the army vehicle was travelling in a residential neighbourhood when it was attacked early on Tuesday.

No group has claimed responsibility for the attack.

Security has been tightened in Islamabad and other cities after the government launched an offensive against the Taliban and al-Qaeda militants in the north-west.

The army has sent thousands of troops into South Waziristan to destroy militant strongholds.

Fighting has been specially fierce around Kotkai, the home town of Taliban leader Hakimullah Mehsud.

The area is out of bounds for journalists and there is little information emerging from there.

Tens of thousands of civilians have fled the region in the last few weeks to escape the fighting.
