Eastern suburbs of the Syrian city of Deir ez-Zor were fully freed from militants of the Islamic State (IS) with the support of Russia and the US-led international coalition, the People's Protection Units (YPG) said in a statement on Sunday.
The YPG spearheads the Syrian Democratic Forces (SDF), an alliance of mostly Kurdish and Arab militias fighting Islamic State with Washington's backing. The SDF offensive in Deir ez-Zor province, which borders Iraq, has focused on territory east of the Euphrates river.
On the western bank, the Syrian military has waged its own attack against Islamic State with support from Iran-backed militias and Russia.
The separate assaults advanced from opposite sides of the river, which bisects oil-rich Deir ez-Zor, mostly staying out of each other's way. The U.S.-led coalition and the Russian military have held deconfliction meetings - to prevent clashes between planes and troops - though the two offensives have sometimes come into conflict.
"The eastern countryside of the city has been fully liberated from Islamic State. SDF(Syrian Democratic Forces, of which the YPG is a part) managed to defeat IS at the eastern banks of Euphrates with the International Coalition and Russia’s support," the statement, published on YPG's website, read.
"We hope that they will continue support SDF forces and strengthen the aerial defence. As the battle against IS comes to an end, we have much to do in order to establish stabilization and peace in Syria," the statement noted.
In early November, the Syrian Armed Forces’ General Staff announced that the city of Deir ez-Zor had been fully liberated from IS with the support of allied forces. It stressed the strategic importance of the liberation of the city as it was located at the crossing of roads connecting the east of the country to the centre and the north.
