FACTBOX: Military and civilian deaths in Iraq

(Reuters) - Seven U.S. personnel were killed in Iraq on Monday, the U.S. military said, making 2007 the deadliest year for U.S. forces in the country.

One of the highest daily tolls in weeks, Monday's deaths took the number of U.S. soldiers killed in Iraq this year to 853. The worst previous year was 2004, when 849 deaths were recorded.

The U.S. military said five U.S. soldiers were killed in two separate roadside bomb attacks in Iraq on Monday near the oil-refining city of Baiji, 180 km (110 miles) north of Baghdad.

A sixth soldier was killed in western Anbar province. The seventh, a sailor, was killed on Monday in an explosion during operations in Salahuddin province, the 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 3,856

Britain 171

Other nations 134

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 76,218 and 83,0343*

# = 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.
