Turkey's state-run media says Turkish police have detained four Islamic State suspects as part of an investigation into a possible attack on the U.S. Embassy in Ankara.
The U.S. Embassy was closed on Monday over an unspecified security threat.
The Anadolu Agency said police detained four suspects on Monday — all of them Iraqi nationals. Two of them were detained on a bus at a security check on a highway linking the Black Sea city of Samsun to Ankara. Two others were detained in Samsun.
