PESHAWAR, Pakistan (AP) -- A Pakistani Taliban suicide bomber blew himself up near a vehicle carrying an area commander of the tribal police in northwest Pakistan on Tuesday, killing four people and wounding at least 52, authorities said.
The attacker, who was on foot, targeted area commander Tehsinullah Khan as his vehicle came out of the headquarters of the tribal police in Jamrud, government administrator Fahad Wazir said. He said Khan survived the attack, but was wounded.
Pakistani Taliban spokesman Mohammad Khurasani later claimed the bombing and vowed in a statement to carry out more attacks in the future.
Wazir said two tribal police officers and two civilians were killed in the attack and that some of the wounded were listed in critical condition at a government hospital.
"Our security forces have been carrying out a major operation against militants. This operation will continue until the terrorists are eliminated," he said.
Jamrud is located 25 kilometers (15 miles) northwest of Peshawar, the capital of Pakistan's Khyber Pakhtunkhwa province.
