FACTBOX: Military and civilian deaths in Iraq

(Reuters) - Six U.S. soldiers were killed on Wednesday when a house rigged with explosives blew up north of Baghdad during a new U.S.-Iraqi offensive targeting al Qaeda guerrillas in Iraq, 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 3,921

Britain 174

Other nations 134

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 80,381 and 87,792*

# = 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.
