A car bomb explosion near a convoy of US troops and Iraqi police outside the capital Baghdad has killed at least five people and wounded 38 others, police say. The attack came on Monday narrowly missing the joint patrol on a highway near the town of Tajji on Baghdad's northern outskirts, local police Lieutenant Sarmed Sami told AFP. No Iraqi police or US soldiers were injured in the attack, he said. In another incident in Baghdad, six people were killed and another 18 were wounded when two bombs exploded simultaneously, one inside and another outside a restaurant in Jadidah, an eastern neighborhood of Baghdad.
