Internet services around Damascus have resumed after a two-day blackout, as violence intensifies.
While Syria’s capital seemed to be back online, it was not clear how much internet access there was elsewhere.
Activists report continued bombardment of eastern suburbs of the capital which have been the focus of a fierce government offensive in recent days.
The government says the city’s airport has reopened but there are still reports of fighting in the area.
Many flights in and out of Damascus were cancelled on Thursday and Friday after heavy fighting on the main road to the airport, which is the country’s busiest.
The BBC’s Lina Sinjab, who is in the capital, says helicopter gunships and MiG warplanes can be heard overhead, reportedly bombarding rebel-held areas.
