July 27 (Reuters) - One American soldier died in a roadside bomb attack in Diyala on Thursday, the U.S. military said.

Another U.S. soldier died on Tuesday in an accident in the northern province of Ninewa, the U.S. military reported.

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:

Other nations 129

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 67,945 and 74,336*

# = 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. IBC says on its Web site that the figure underestimates the true number of casualties.
