(CNN) -- A NATO drone helicopter went down in Libya on Tuesday, NATO spokesman Commander Mike Bracken said, declining to say whether it was shot down or experienced mechanical problems.
Libyan state television reported that an "Apache helicopter was downed in the area of Majr in Zliten," claiming it was the fifth NATO aircraft to be downed.
An Apache is an attack helicopter. Bracken specifically denied that NATO had lost an attack helicopter.
