A search and rescue operation is underway in southern Morocco after two U.S. service members were reported missing off the southern coast of the North African nation during annual training exercises. A defense official told CBS News that the soldiers were last seen near ocean cliffs near the Cap Draa Training Area. Initial reports indicate they may have fallen into the ocean, the official said. No foul play is suspected, sources told CBS News. The names of the soldiers and further details have not yet been released. Ground teams, aerial assets and maritime elements from the Moroccan Royal Armed Forces, U.S. Armed Forces, and other African Lion participants are involved in the search, the defense official said.
