Blast in Iraqi Capital Kills 72

Iraqi police say 72 people have been killed in a bomb blast in Baghdad, less than a week before U.S. troops are to withdraw from Iraq’s urban areas.

More than 160 people were injured in Wednesday’s blast, which tore through a market in the mostly Shi’ite district of Sadr City.  Officials say the attacker hid the bomb under a cart of vegetables loaded on a motorcycle.
