There were rumors about him still being captive alive, but two militant groups affiliated with the ISIS confirmed that he was murdered. Local authorities tried to negotiate his freedom with the terrorists but their attempts remained futile. The war in Syria, which is showing signs of war of hatred, is turning into a sectarian conflict as thousands of terrorists supported by US regional allies have turned more violent than ever in their fight against Syria. Many blame Washington for presence of terrorists and extremist groups in the Middle East which are seen as a legacy of US - led 2003 invasion on Iraq which left the war - torn country exposed to an even more complicated security situation that it was experiencing before. The war in Syria started in March 2011, when pro - reform protests turned into a massive insurgency following the intervention of Western and regional states. The unrest, which took in terrorist groups from across Europe, the Middle East and North Africa, has transpired as one of the bloodiest conflicts in recent history. As the foreign - backed insurgency in Syria continues without an end in sight, the US government has boosted its political and military support to Takfiri extremists.
