Islamic State routed in last major stronghold

Pro-government forces defeated the Islamic State group in its last major stronghold in Syria, state media and a monitoring group reported Sunday, leaving the militants to defend just strips of desert territory in the country and a besieged pocket outside the capital, Damascus.

Also Sunday, more than two dozen civilians were killed as government forces and rebels traded fire across fronts in Damascus and Homs, Syria’s third-largest city.

The intensified violence is testing an accord by Russia, Turkey and Iran to suppress fighting in Syria before the resumption of political talks in Geneva between the government and opposition, set for Nov. 28.

Eight civilians were killed in rebel shelling on Homs, which also put the city’s al-Walid flour mill out of service, Syria’s SANA news agency reported. It added that another two were killed by shelling or rocket fire on Damascus.

At least 17 civilians were killed in government shelling and airstrikes on the Eastern Ghouta suburbs of Damascus, which remain under opposition control, according to the Britain-based Syrian Observatory for Human Rights. The civil defense search and rescue group, more popularly known as the White Helmets, said one of its volunteers was killed in the line of duty by a rocket.

Residents in the Ghouta region have suffered under a government bombardment since rebels tried to storm a military position Tuesday. At least 77 civilians have been killed, according to the Observatory.

Despite its recent defeats, the extremist group’s media apparatus has remained active, and its fighters are likely to keep up their insurgency from desert areas.
