The Syrian Civil War became a focus for Sunni fighters waging jihad on Shia . The al-Nusra Front is the largest jihadist group in Syria.  The Muslim Brotherhood in Egypt has called for jihad against the Syrian government and against that government's Shi'ite allies.  Saudi Arabia backs the jihad against the Shia in Syria using proxies.  Sunni jihadi converge in Syria from Saudi Arabia, Bahrain, Yemen, Kuwait, Tunisia, Libya, Egypt, Morocco, as well as other Arab states with Chechnya, Pakistan, Afghanistan and Western countries.
