Insurgent ambush of Iraqi police kills 29
The blast at the house was triggered as officers were about to enter, a local police official said. Ten neighbouring houses collapsed from the blast and several residents were believed trapped underneath the rubble. Seven policemen were among the 29 dead.
The police official said the attack was "evidently an ambush" and that "massive amounts of explosives" were used. He said the explosion was apparently triggered by remote control.
