A car bomb killed five people on Saturday between the Iraqi cities of Najaf and Kerbala, sites of twin suicide car bombings a week ago, the chief of police in Najaf said. Ghalib al-Jazairi said those killed were civilians but the bomb in the town of Khan al-Nus appeared to have been aimed at a U.S. military convoy. A witness confirmed that, saying a Landcruiser vehicle blew up as the military convoy passed. Khan al-Nus lies about 30 km (20 miles) north of Najaf. Sunday's bombings in Najaf and Kerbala killed more than 60 people and wounded nearly 200.
