A group of Takfiri militants in Syria have reportedly killed a senior commander of the so - called Free Syrian Army(FSA) amid growing infighting among the foreign - sponsored armed groups in the country.Qassem Saadeddine, an FSA spokesman, said on Thursday that the militants killed Kamal Hamami, known by his nom de guerre Abu Bassel al - Ladkani, following a meeting with him to discuss battle plans in the Syrian port city of Latakia. According to Saadeddine, the militants have also threatened to kill all senior commanders of the foreign - backed armed group. Over the past months, rivalries and infighting have been on the rise among highly - divided militants operating inside Syria. On June 5, dozens of militants were killed and wounded as violent infighting broke out between several Takfiri groups in Syria’s northwestern province of Idlib, according to locals. Foreign - sponsored militancy in Syria has taken its toll on the lives of many people, including large numbers of Syrian soldiers and security personnel, since March 2011. Western powers and their regional allies including the Israeli regime, Turkey, Saudi Arabia and Qatar are partners in supporting anti - Syria militant groups, including al - Qaeda - linked terrorists, to destabilize Syria and overthrow the government of President Bashar al - Assad. In an interview with Syrian dailyAl - Thawra published on July 4, President Assad said the opposition and their foreign supporters have “exhausted all their tools” in a conspiracy against Syria.
