At least 56 people have been killed and more than 200 others injured in a wave of bombings across Baghdad and nearby towns, Iraqi officials said today.
More than a dozen attacks - mostly car bombings - highlighted increasing sectarian tensions in Iraq a decade after the war began.
The attacks came on the eve of the anniversary of the US-led invasion, which started before dawn on March 20 2003.
One of the deadliest of the attacks hit near a main gate to the heavily-fortified Green Zone, which houses major government offices and the embassies of several countries, including the United States and Britain.
Police and hospital officials provided the casualty toll.
