An armed boy belonging to the anti-Qaeda Sahwa group watches people grieving over the bodies of relatives killed in a suicide bomb attack in the Sunni Arab village of Bu Mohammed in the restive Diyala province north of Baghdad on April 17, 2008. A suicide bomber blew himself up in a crowd of mourners in Bu Mohammed, killing at least 51 people in one of the biggest insurgent attacks in violence-wracked Iraq this year.
