FACTBOX: Military and civilian deaths in Iraq

(Reuters) - A roadside bomb killed three U.S. soldiers and an interpreter late on Tuesday in Nineveh province, northwestern Iraq, the U.S. military said.

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 4,109

Britain 176

Other nations 137

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 85,153 and 92,883*

# = 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.

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