PESHAWAR (Pakistan) - Two suspected suicide bombers killed at least 40 people in an attack at the office compound of a senior government official in an area along Pakistan's Afghan border Monday, officials said. "The blasts destroyed many rooms in the compound and our reports are 40 people were killed and many wounded," a senior security official in the region said. Amjad Ali Khan, the top government official in the Mohmand region who appeared to be the target of the attack, earlier told Reuters by telephone that it appeared to be a suicide attack. "There were two bombers. They were on foot. The first blew himself up inside the office of one of my deputies while the second one set off explosives when guards caught him." Mohmand is one of the lawless tribal regions in Pakistan's northwest. Pakistan's army has said its offensives have weakened al-Qaeda-linked Pakistani Taliban militants seeking to destabilize the US-backed government. But analysts say they often melt away during assaults.
