Two suicide bombers have rammed their cars into two checkpoints in Baghdad, killing at least 10 people. In the first attack, the bomber blew up his car against a joint Iraqi military and police checkpoint in central Baghdad's Kharmana Square, killing eight people, including members from the security forces. The blast left 25 others wounded. A few minutes later, a second bomber slammed his car into an Iraqi army checkpoint in southwestern Yarmuk district, killing two people, one civilian and a soldier. Two more were wounded in the attack.
