Sept 29 (Reuters) - A U.S. soldier was killed by small arms fire while conducting combat operations in southern Baghdad, the U.S. military said on Saturday. Another soldier was killed by gunfire in Diyala province, north of the capital.

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 3,803

Britain 170

Other nations 130

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 74,339 and 81,025*

# = 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 that 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.
