June 30 (Reuters) - The U.S. military said four U.S. soldiers based in Baghdad have died of combat-related injuries on Monday. It gave no further details.

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

U.S.-LED COALITION FORCES:

United States 4,321

Britain 179

Other nations 139

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 92,435 and 100,911*

# = 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 website the figure underestimates the true number of casualties.
