22 killed in suicide bombing

At least 22 people are dead after a suicide bomber blew himself up in Baghdad.



Officials say the bomber detonated the bomb among a group of Iraqis collecting humanitarian aid in a mainly Shiite area in Baghdad.



According to a Baghdad military spokesman, the bombing occurred just after noon as Iraqi police were distributing aid parcels in the central neighbourhood of Karradah.



The attack is said to be the latest in a series of high-profile bombings as the U.S. military scales back its forces ahead of a planned withdrawal by the end of 2011.



Some police, women and children were among those killed.
