A Taliban bomber rammed his car into a police check post in Pakistan's northwest on Wednesday, killing five policemen, Reuters reported. The blast on the outskirts of the main northwestern city of Peshawar is the latest in a string of attacks mounted by the militants. "The policemen were on their routine duty when the bomber driving the car from the tribal area detonated explosives near the check post," police official Najmul Hasan told Reuters. "Five people have been killed and eight wounded. All of them are policemen." Peshawar police chief Liaquat Ali said the attacker was apparently trying to make his way into the city but decided to set off his explosives when he was stopped.
