Sept 16 (Reuters) - Four U.S. soldiers were killed by an explosion near their vehicle in Diyala province northeast of Baghdad on Friday, the U.S. military said.

Also on Friday, one U.S. soldier was killed and four were wounded in a bomb attack while they were on patrol, the military said. It gave no precise location for the attack.

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 3,781

Britain 169

Other nations 129

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 71,302 and 77,852*

# = 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.
