KHAR, Pakistan — Two suicide bombers struck outside a government office Friday in a tribal region where Pakistan's army has fought the Taliban, killing more than 50 people and wounding more than 100, officials said.
The attack, one of the deadliest in Pakistan this year, indicated that militants remain a potent force in the country's tribal belt bordering Afghanistan despite army offensives.
The US has praised Pakistan for taking on Islamist extremists that use the tribal region to plan attacks on Western troops across the border, but the militants have often retaliated on Pakistani soil.
The bombers detonated their explosives near the Yakaghund village office of Rasool Khan, a deputy administrator of the Mohmand tribal region who escaped unharmed. At least one bomber was on a motorcycle.
Nearby, officials were distributing wheelchairs to disabled people and equipment to poor farmers, said Mohmand's chief administrator, Amjad Ali Khan. He said more than 50 people were killed and more than 100 were wounded.
