Syrian troops seized a suburb of the city of Deir ez-Zor in eastern Syria on Sunday, tightening the noose around Islamic State militants, a military source said, as cited by Reuters.

The Syrian army has cut Islamic State’s main supply line in the city of Deir al-Zor after taking control of the al-Jafra district, Russia’s RIA news agency cited an unnamed source as said.

Oil-rich Deir al-Zor province, which borders Iraq, is Islamic State’s last major foothold in Syria.

The Syrian army pushed into Deir al-Zor city this month, with Russian air power and Iran-backed militias, breaking an Islamic State siege of an enclave that had lasted three years.
