The U.S. military is positioning troops to be ready to respond to unrest in as many as 18 locations, Defense Secretary Leon Panetta said.

Panetta said there were certain hotspots the Pentagon was “paying particular attention to,” in an interview with Foreign Policy on Friday.

Separately, a U.S. defense official told the publication that the Pentagon is considering sending 50 Marines to guard the embassy in Sudan, where protesters objecting to a U.S.-made anti-Islam film breached the American and German embassies on Friday. The Department of Defense has already announced it is sending 100 Marines to Libya and Yemen.
