June 20 (Reuters) - A roadside bomb hit a NATO vehicle in southern Afghanistan on Wednesday, killing three soldiers, the alliance said.

The three soldiers were Canadians, a senior Canadian military official said.

Here are the latest figures for foreign military deaths in Afghanistan since the Taliban government was toppled in 2001:

NATO/U.S.-LED COALITION FORCES:

United States 405

Britain 60

Canada 60

Spain 21

Germany 21

Other nations 42

TOTAL: 609

Last year's fighting was the bloodiest in Afghanistan since U.S.-led forces overthrew the Taliban in 2001 and violence is increasing this year.

More than 4,000 people were killed in fighting in 2006, a quarter of them civilians and about 170 of them foreign soldiers killed in fighting or in accidents while on patrol. Sources: Reuters/icasualties (www.icasualties.org/oef)
