KABUL, Afghanistan — A helicopter crash in southern Afghanistan killed five American service members, officials said Tuesday.
Monday night's crash brought the number of U.S. troops killed that day to seven, making it the deadliest day for U.S. forces so far this year. Two U.S. special operations forces were gunned down hours earlier in an insider attack by an Afghan police officer in eastern Afghanistan.
In the helicopter crash, the NATO military coalition said in a statement that initial reports showed no enemy activity in the area at the time. The cause of the crash is under investigation.
All five people aboard the UH-60 Black Hawk were killed, said Maj. Adam Wojack, a spokesman for the international military coalition.
A U.S. official said all five were American. The official said the helicopter went down outside Kandahar city. The official spoke to the Associated Press on condition of anonymity because the information had not been formally released.
