The militants are said to have counter-attacked, targeting nearby villages.
The fighting comes after the government recaptured most of the surrounding province of Deraa from rebel factions.
Rebel commanders agreed on Friday to surrender their heavy weapons and begin handing over towns as part of a Russian-brokered agreement.
In return, the Russian military is believed to have guaranteed the safe return of the 320,000 civilians who fled their homes after the government’s offensive began on 19 June, as well as the evacuation to rebel-held parts of north-western Syria for people who wish to leave.
An IS-affiliated group, the Khalid Ibn al-Walid Army, has controlled the south-western corner of Deraa province since 2014, when jihadists overran vast swathes of Syria and neighbouring Iraq and proclaimed the establishment of a “caliphate”.
