Six Nato soldiers have been killed in Afghanistan in one of their deadliest days this year as the US commander led calls for swift governance following a major offensive against the Taliban.

The military deaths bring to 107 the number of foreign soldiers who have died in Afghanistan so far this year, according to an AFP count.

More than double the number of foreign troops perished during the first two months of this year compared to the same period in 2009, as thousands more soldiers pour into Afghanistan as part of a strategy to end the war.

One of the six Nato troops killed was a British soldier, who was shot dead in southern Afghanistan, but nationalities of the other five were not released.

Bomb attacks killed another 10 Afghans Monday in southern Afghanistan, where Nato commanders are concentrating a US-led surge that will bring the overall number of foreign troops in Afghanistan to 150,000 by August.
