DAMASCUS (Worthy News)-- The Islamic State (IS) seized control of the city of Deir ez-Zor, the sixth largest city in Syria, when rival jihadist groups, Jabhat al-Nursa and Ahrar al-Sham, withdrew their forces. They now control nearly 100 percent of the Deir Ez-zor province.
According to the Britain-based Observatory, which relies on a network of activists and medics on the ground, ISIS jihadists are now in control of "95 to 98 percent of Deir Ezzor province".
The Observatory said that rivals of ISIS, including fighters of Al-Qaeda’s Syria affiliate al-Nusra Front, lost control after negotiations failed with the jihadists who last month declared a "caliphate" straddling Syria and Iraq.
"Fighters from al-Nusra Front and the Islamist rebel movement Ahrar al-Sham withdrew from their bases in the city, while others pledged their loyalty to ISIS," the Observatory said.
"IS killed the Deir Ezzor chief of al-Nusra, and raised their flag in the city," it added.
