KABUL -- The NATO-led coalition says bomb attacks have killed three American troops in Afghanistan.
The international force says two American troops were killed in an explosion in the troubled nation's east on Friday.
Another U.S. service member was killed the same day in a bombing in the south.
The coalition announced the deaths in a statement Saturday. No further details were released.
The deaths bring to 28 the number of American service members killed in Afghanistan this month, according to an Associated Press count.
