Police officials say the suicide bomber targeted a vehicle carrying committee chief Fateh Khan Saturday in restive Buner district in Khyber-Pakhtunkhwa province.
The attack also killed three guards and wounded several other people.
Buner district is believed to be a hiding place for the Pakistani Taliban. It borders the the Swat Valley, where Taliban gunmen last month seriously wounded a 14-year-old girl who spoke out against the militant group and in favor of education for women. VoA.
