A car bomb on Saturday killed at least 10 people and wounded 15 others at a crowded market in a northwestern Pakistani tribal town, officials said.
The bomb ripped through the main market in Darra Adam Khel, near to a local anti-insurgent peace committee office, the officials added.
"At least 10 people were killed and 15 others were wounded," tribal security official Shirin Gul told AFP.
"The target was the local peace committee," Gul said, adding that nobody has yet claimed responsibility for the bombing.
Two other officials confirmed the bombing and the death toll and said some of the wounded were shifted to other cities for treatment as local health facilities were not sufficient.
The peace committee comprised a breakaway group of former militants who ditched their Taliban colleagues and formed a militia supporting local elders and government efforts against militancy, a local intelligence official said.
Semi-autonomous Darra Adam Khel lies between the northwestern towns of Peshawar and Kohat and had experienced several suicide attacks and bombings blamed on Taliban militants.
