Dec 28 (Reuters) - A U.S. soldier died of wounds inflicted by a roadside bomb in northern Baghdad on Sunday, the U.S. military said.

Following are the latest figures for soldiers and civilians killed in Iraq since the U.S.-led invasion in March 2003:

U.S.-LED COALITION FORCES:

United States 4,218

Britain 178

Other nations 138

IRAQIS:

Military Between 4,900 and 6,375#

Civilians Between 90,147 and 98,413*

# = 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. (Writing by David Cutler, London Editorial Reference Unit;)
