The U.S.-led campaign to oust former Iraqi President Saddam Hussein, Operation Iraqi Freedom, began on March 19-20, 2003.
The gatherings today were generally smaller than expected.
In London, about 15,000 people joined in a march to Trafalgar Square. Speakers called for a withdrawal of coalition troops from Iraq, saying the fighting could spread to neighboring Iran.
Protests were also held in Tokyo, Stockholm, Copenhagen, Sydney, and elsewhere.
Antiwar marches in South Korea and Malaysia are planned for March 19.

THE SOUND OF THE GUNS: In the days just before and after the beginning of Operation Iraqi Freedom on March 19-20, 2003, RFE/RL worked hard to cover the unfolding conflict. RFE/RL correspondent RON SYNOVITZ was embedded with the 3rd Brigade Combat Team in the U.S. Army's 3rd Infantry Division as it crossed the border from Kuwait and drove deep into Iraq. Synovitz stayed with the U.S. troops through mid-April, covering the battle for Baghdad and the toppling of Saddam Hussein's regime.
RFE/RL correspondent CHARLES RECKNAGEL also covered the beginning of the war from Kuwait and Iraq. Here are some links to his reports:
