Rescue workers in western Baghdad are continuing to sift through the rubble of at least 10 houses that collapsed late Tuesday when insurgents booby-trapped one building and detonated it during a police raid.
Authorities say at least 29 people, including six policemen, were killed in the blast. Four other policemen are missing and more than 20 people were wounded.
Iraqi authorities say insurgents lured police to the house, which was rigged with about 800 kilograms of explosives, and then remotely detonated it when the officers were inside.
The attack capped off a blood day in Iraq Tuesday, with at least 23 other police and National Guardsmen killed in a series of attacks in the so-called Sunni Triangle region north and west of Baghdad.
