 According to some reports, as of mid-2013, the Syrian Civil War has become "overtly sectarian" with the "sectarian lines fall most sharply" between Alawites and Sunnis.With the involvement of Lebanese Shia paramilitary group Hezbollah, the fighting in Syria has reignited "long-simmering tensions between Sunnis and Shi’ites" spilling over into Lebanon and Iraq.Ex-Ambassador Dimitar Mihaylov further claims that the current post-Arab Spring situation (encompassing ISIS, the Syrian civil war, Yemen, Iraq and others) represents a "qualitatively new" development in the history of Shi'a-Sunni dynamics.
