Islamabad, Pakistan (CNN) -- A bomb detonated, injuring a provincial lawmaker and three others in northwest Pakistan on Wednesday, police said.
The target was provincial lawmaker Aurangzaib Khan, police official Kalam Khan said. The lawmaker had just left his home with three companions when a remote-controlled bomb exploded as his car passed in Peshawar.
Aurangzaib Khan is a member of the ruling Awami National Party in Pakistan's Northwest Frontier Province. The ANP is a secular party that has been an outspoken critic of the Taliban.
The Taliban has targeted several members of the ANP, including Aurangzaib Khan's brother, Alamzaib Khan, who was killed last February in another bomb blast.
In December, a suicide attacker killed ANP member and provincial lawmaker Shamshir Ali.
Aurangzaib Khan was in stable condition, hospital official Dr. Abdul Hamid Afridi said. One of the remaining three injured was in critical condition.
