Authorities shut down YouTube after the airing of leaked audio in which the foreign minister, the intelligence head, and a top general are heard discussing possible military operations in Syria. Foreign Minister Davutoğlu said publicly yesterday that Turkey would take steps to protect its security, including an operation in Syria to protect the tomb of Süleyman Shah. In the unverified recording, an official says: "An operation against ISIL has international legitimacy. We will define it as al Qaeda .... When it comes to the Suleyman Shah tomb, it's about the protection of national soil." Two suspected ISIS (ISIL) members and two policemen were injured during a raid in Istanbul on March 25. An intelligence expert said that the Iran-backed Tawhid-Salam is the most dangerous terrorist group Turkey has faced.
