Pakistani officials say a Taliban suicide bomber has attacked the compound of a rival militia group and killed at least 13 people.
A senior government official said the attacker drove a car filled with explosives into the headquarters of anti-Taliban militant commander Nabi Hanfi, in the Orakzai tribal area, on Thursday. At least six people were wounded in the attack.
A Taliban spokesman claimed responsibility for the attack. He said Hanfi, who survived the attack, would remain on the Taliban's list of targets.
The Taliban have waged a decade-long struggle for power in Pakistan's northwest tribal regions, in an attempt to bring the area under Islamic law. Some militia leaders, like Hanfi, have partnered with the government to oppose those efforts.
