The citizens of Mayadin, located in the east of Deir ez-Zor Province, on Saturday attacked the headquarters of the terrorist group and killed two militants.
The terrorists have kidnapped and tortured several civilians in the militant-held district.
The report came as infighting among rival Takfiri groups intensifies across Syria. Al-Qaeda-affiliated militants have reportedly gained the upper hand against the so-called Free Syrian Army (FSA) in the north of the Arab country.
According to reports, the terrorist Islamic State of Iraq and the Levant (ISIL), an al-Qaeda offshoot, has now control over most parts of Syria’s northern town of Raqqa.
Meanwhile, heavy clashes are underway between the ISIL and the so-called Islamic Front near Syria’s Bab al-Salameh border crossing with Turkey, north of Aleppo.
Reports also indicate that civilians in Raqqa and Aleppo have been trapped in their houses due to the heavy infighting among different extremist groups.
The infighting underscores how complicated the insurgency against Assad has become.
Syria has been gripped by deadly unrest since March 2011. 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.
More than 120,000 people have been killed and more than four million other Syrians will be forced out of their homes in 2014 by the escalating conflict in the country.
