(Reuters) - Two U.S. soldiers were killed and two wounded when gunmen opened fire after a roadside bomb exploded in Salahuddin province on Tuesday, the U.S. military said.

One U.S. soldier was killed and two were wounded by an explosion in Anbar province in western Iraq on Monday, it said.

Following are the latest figures for military deaths in Iraq and Iraqi civilians killed in attacks since the U.S.-led invasion in March, 2003:

U.S.-LED COALITION FORCES:

United States 3,885

Britain 173

Other nations 134

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 77,846 and 84,812*

# = 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.

The U.S-led military coalition toll includes casualties from Iraq and the surrounding area where troops are stationed.
