Iraq: Bomb kills 4 at Baghdad security checkpoint

Iraqi authorities said that a bomb killed four people and wounded nine others at a security checkpoint in eastern Baghdad on Saturday. Police and medics said that the dead included three Iraqi police commandos and a member of an armed Sunni group that has turned against al-Qaida in Iraq. The injured included seven Iraqi security personnel and two bystanders. The police and medics spoke about the attack on condition of anonymity because they were not authorized to speak to the media. On Friday, a car bomb ripped through a crowded commercial district in Dujail, a mainly Shi'ite town north of Baghdad. Iraqi officials say at least 32 people died.
