Terrorists in Syria have stepped up their attacks on rival militants groups fighting against the Syrian government.
The foreign-backed militants continued their fighting in Dayr al-Zawr, the largest city in the eastern part of Syria, opposition sources said on Tuesday.
The ISIL terrorists pushed militants of the al-Nusra Front and other armed groups out of the city.
The ISIL reportedly killed the leader of al-Nusra Front and raised their flag in the city, forcing members of armed groups there to either flee or to surrender.
Another part of the city, including the airport, as well as a number of nearby villages remain under the control of Syrian army soldiers.
The ISIL militants have captured some areas in Iraq and Syria and are fighting against soldiers of the Iraqi and the Syrian governments.
Syria has been gripped by deadly violence since March 2011. Over 160,000 people have reportedly been killed and millions displaced due to the violence fueled by the foreign-backed militants.
According to reports, the Western powers and their regional allies -- especially Qatar, Saudi Arabia and Turkey -- are supporting the militants operating inside Syria.
