Four soldiers serving with the International Security Assistance Force in Afghanistan have been killed.
Two were killed in an insurgent attack in the south of the country.
A third soldier was killed by an improvised explosive device in southern Afghanistan, and the fourth died from an unspecified non-battle-related injury.
None of the soldiers killed was identified, either by name or country of origin.
Nineteen soldiers from the NATO-led force have died so far this month in Afghanistan.
More than 2990 troops from the coalition force, including some 1959 Americans, have died in Afghanistan since the US-led military intervention began in 2001.
