A series of bombs struck US and Iraqi security forces in Baghdad and the northern city of Mosul on Monday, killing at least 32 people and wounding dozens more, Iraqi officials said.

The bloody attacks were a grim reminder of the dangers facing Iraqis as they try to take over their own security. The Iraqi parliament last week approved a security pact with the United States that would let the Americans stay in Iraq for three more years to help maintain stability.

At least 16 people were killed and 46 wounded in a nearly simultaneous double bombing near a police academy in eastern Baghdad.

A suicide attacker detonated his explosives vest packed with ball bearings at the entrance to the academy, then a car bomb exploded about 150 yards away, apparently aimed at those responding to the initial blast, the US military said.

The blasts occurred within minutes of each other on Palestine Street, according to police and witnesses.

Bloodied police uniforms and a military boot left by victims were scattered with the crumpled metal hulk of the car bomb on the charred street in the aftermath of the bombing, according to Associated Press Television News footage.

The attacker apparently was a teenage boy whose head was taken to a local hospital, a police officer said. An AP photographer saw the head and confirmed it appeared to be a teenage boy.
