THE Syrian army dealt a triple blow to Isis in eastern Deir Ezzor province yesterday.
The army, backed by attack helicopters, smashed through the death cult’s lines in the last districts it holds in the provincial capital, recapturing all of the industrial district.
They also secured the university building in al-Harabisheh district and advanced 100 metres beyond the city stadium.
In the southern desert of the province, troops backed by Lebanese Hezbollah guerillas and Iranian-Afghan volunteers surrounded the Isis-held T2 airbase on three sides.
On Tuesday Isis used a sandstorm as cover for a sneak attack across the Euphrates river on the recently captured town of al-Mayadeen, downstream from Deir Ezzor.
But Syrian troops and the Palestinian refugee Jerusalem Brigades — newly reinforced with some 500 volunteers from the local Busraya tribe — fought off the attack, killing dozens of the extremists and taking several prisoner.
