Anti-regime forces in Syria are entering the centre of Damascus on Sunday which has been lost by the Assad regime, Anadolu news agency reported.
Protesters rose against the regime late Saturday in neighbourhoods, while regime forces pulled out from critical sites such as the Defense Ministry, Interior Ministry and the international airport.
With the entry of protesters into crucial areas, the regime had lost most of its control over the capital.
Prisoners in the Sednaya Prison in Damascus, known for its association with the regime and notorious torture practices, were freed by demonstrators who stormed the facility.
