Syrian President Bashar Assad's top aide and adviser, General Mohammed Suleiman, was assassinated on Friday, according to Arab news sources.
Syrian authorities tried unsuccessfully to prevent publication of the news. The country's Albawaba newspaper, which reported the incident, speculated that Israel might have been behind the killing.
Apparently, someone, somewhere, did not want the Israeli/Syrian back-channel political dialogue to continue.
Syrian President Bashar Assad is due in Tehran for top level meetings in about a week or so.
