Three Afghanistan National Army soldiers have been reported missing from a training exercise at a Cape Cod military base.

U.S. military officials say the soldiers had been participating in a Regional Cooperation training exercise at Joint Base Cape Cod. They arrived at Camp Edwards on Sept. 11 and were last seen at the Cape Cod Mall in Hyannis.

The soldiers were reported missing by base security personnel on Saturday night. Base and exercise officials are working with local police and state authorities to locate them.

Military officials say the soldiers aren't a threat to the public.

The Regional Cooperation training exercises have been held annually since 2004 and involve six different nations including the U.S. The exercise, which is held by U.S. Central Command, wraps up on Wednesday.
