Rebel fighters form the Democratic Forces of Syria, use a walkie talkie and a tablet near the al-Hawl area where fighting between them and ISIS fighters are taking place in south-eastern city of Hasaka, Syria November 10, 2015.

A recently formed U.S.-backed Syrian rebel alliance captured on Friday the town of al-Houl in Hasaka province that was held by Islamic State of Iraq and Syria fighters, a spokesman for the Kurdish fighters, part of the grouping, said.

Redur Xelil, who is in the town, told Reuters that ISIS have fled the town which is close to Iraqi border.

Seperately, Syrian government forces captured the village of Tel Hadya in the northern province of Aleppo on Friday, a monitoring group and state media said, in the latest territorial gains reported against insurgents in the area.

The reported advace brought pro-government forces closer to the main highway that links Syria’s major cities, building on other gains made in the area with support from Russian air strikes.

There was no immediate comment from rebels, including al Qaeda’s Nusra Front, who have have been in control of the area.

Fighting has intensified even as world and regional powers prepare to meet in Vienna in a bid to step up diplomatic efforts to the end the four-year-old conflict.

Syrian state TV reported the takeover of Tel Hadya and the Britain-based Syrian Observatory for Human Rights, which monitors the conflict using sources on the ground, confirmed it.

The advance came a day after the Syrian army backed by Lebanese Hezbollah fighters, Iranian troops and Russia air raids took the nearby town of Al Hader, effectively bringing government forces in control of most of the southern Aleppo countryside.

“The southern Aleppo countryside is falling hill after hill… the army is advancing quickly,” the Observatory’s Rami Abdulrahman told Reuters.

The advances could provide a launching pad to push further against insurgent strongholds in mainly rebel-held northwestern Syria.

The Kremlin believes the Syrian army’s offensive is effective and that, with the help of Russian air strikes, the Syrians are making good progress, Russian RIA Novosti news agency said on Friday.

Russia launched its air campaign in support of President Bashar al-Assad on Sept. 30, ostensibly to fight ISIS militants. But raids have mainly targeted other insurgent groups, some foreign-backed, in the west of the country, the United States says.

The campaign appeared to be making little headway in terms of captured territory until the latest advances in Aleppo province. Government troops also broke an ISIS siege on an airbase elsewhere this week.

Rebels have made advances elsewhere.
