PESHAWAR, Pakistan: A suicide car bombing targeting Pakistani troops killed 41 people yesterday, the fourth grisly militant attack in just over a week, as the Taliban pledged to mobilize fighters across the country for more strikes.

The Taliban also claimed responsibility for the 22-hour weekend attack on the nation's heavily fortified army headquarters, saying a cell from Pakistan's most populous province carried out the raid.

The claim that a Punjabi faction of the Pakistani Taliban was behind that strike is a sign the insurgents have forged links with militants outside their main strongholds in Pashtun areas close to the Afghan border, increasing their potency.
