RNA - The sources said that ISIL detonated three bomb-laden suicide vehicles near the defense lines of Tahrir al-Sham, a coalition formed by Al-Nusra Front (also known as Fatah al-Sham Front or the Levant Liberation Board), inflicting major losses on the rival group.
The sources added that heavy fighting is underway between ISIL and Tahrir al-Sham in the streets of Haifa, Safouriyeh, the 15th street and the main street in Yarmouk.
They said that the clashes have set fire at vast regions in the camp.
Reports from the camp said that a number of terrorists from both sides have been killed in the clashes.
In November, the Syrian government gave a last ultimatum to the ISIL and Al-Nusra terrorists to leave Yarmouk or wait for the army's crushing attack.
The AMN website reported that the Syrian government had in early November given a month to the two terrorist groups to leave the camp, but after their refusal launched mortar and missile attacks against them as a warning.
ISIL controls nearly 80 percent of Yarmouk camp and al-Nusra Front is in charge of the remaining 20 percent.
Al-Nusra Front is trapped in the siege of ISIL and both of the terrorist groups are trapped in the circle of Syrian government forces.
