The U.S.-led coalition said Tuesday three of its troops have been killed in a roadside bomb blast in southern Afghanistan.
The coalition did not release any other details, including the nationalities of the troops or the blast's location.
Most of the troops in the coalition are American but it does include forces from several other countries.
Taliban and other militant bombs have grown larger and deadlier this year.
More U.S. soldiers have died in Afghanistan already in 2008 than in any year since the 2001 U.S.-led invasion. At least 127 U.S. forces have died, as have 99 from other coalition countries.
