Sept 19 (Reuters) - A U.S. soldier was killed during a small arms fire attack while conducting combat operations in southern Baghdad on Tuesday, the U.S. military 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 3,785

Britain 169

Other nations 129

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 72,596 and 79,187*

# = 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.
