Members of the Syrian government forces march near the town of Qumhanah in the countryside of the central province of Hama, on April 1, 2017.

:: The Syrian army and allied fighters drove the ISIS from their last positions in the central province of Hama on Wednesday, October 4, after heavy fighting, a monitor said.

The Syrian Observatory for Human Rights, a Britain-based monitor of the war, said ISIS was no longer present anywhere in the province for the first time in 3 years.

The army, backed by ally Russia, launched a campaign against ISIS in Hama in early September, capturing some 50 villages and the strategic town of Uqayribat, the Observatory said.

“On Wednesday, regime forces managed to take control of all the last remaining villages in the hands of Daesh (ISIS) in eastern Hama province after more than a month of fierce clashes between the two sides,” Observatory director Rami Abdel Rahman said.

The monitor said more than 400 ISIS fighters and nearly 190 Syrian soldiers and allied militiamen had been killed in the fighting.

There was no immediate announcement in Syrian state media, but the Al-Watan newspaper, which is close to the government, reported that “the army has taken complete control of eastern Hama province.”

“Daesh is no longer present in Hama province,” it added.

The government holds large parts of Hama province, and all of the provincial capital.

But ISIS and other rebels hold pockets of territory in the northeast and south.

ISIS’ loss of Hama province comes after they were forced in June to withdraw from their last positions in Aleppo province further north.

The militant group is also facing multiple offensives elsewhere in the country.

The US-backed Syrian Democratic Forces, an alliance of Kurdish and Arab fighters, is battling to oust ISIS from their onetime stronghold of Raqqa.

The SDF is also fighting ISIS in neighbouring Deir Ezzor province, where the regime is waging its own campaign against the militant group as well.

More than 330,000 people have been killed in Syria since the conflict began with anti-government protests in March 2011.
