At least three people were killed and five others injured today when a suicide bomber in an auto-rickshaw blew himself up near a group of policemen in the provincial capital of Peshawar in northwest Pakistan. The incident comes a day after 14 people died in a similar attack in the city. The attack was the latest in a string of strikes that have killed more than 300 people over the past six weeks.<br/><br/>Peshawar police chief Liaqat Ali Khan said the bomber apparently seemed to be heading somewhere else but blew himself up when he was stopped by the policemen.
