May 12 (Reuters) - A roadside bomb killed a U.S. soldier on patrol in northwestern Baghdad on Sunday, the U.S. military said.

Two other U.S. soldiers died in the last few days in Iraq in separate non-hostile incidents, the U.S. military reported.

Following are the latest figures for soldiers and civilians killed since the U.S.-led invasion in March, 2003:

U.S.-LED COALITION FORCES:

United States 4,076

Britain 176

Other nations 136

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 83,521 and 91,094*

# = Think-tank estimates for military under Saddam Hussein killed during the 2003 war. No reliable official figures have been issued since new security forces were set up in late 2003.

* = From www.iraqbodycount.net (IBC), run by academics and peace activists, based on reports from at least two media sources. The IBC says on its Web site the figure underestimates the true number of casualties.
