Over 4,000 Daesh militants, reinforced by tanks, have started an offensive to retake the key Syrian city of Palmyra after regrouping themselves, the Russian Centre for Reconciliation in Syria says.
According to the Russian military, the militants have received considerable reinforcement, including heavy military hardware from the regions of Raqqa and Deir ez-Zor.
The statement by the Russian military says:
Daesh has dispatched a considerable force to Palmyra from the area of Raqqa, where militants, backed by the US and the international coalition seized combat action against the terrorists this week
The Reconciliation Centre notes that the Syrian Army is engaged in fighting the militants.
Despite heavy losses in manpower and [military] hardware, the terrorists seek to come as close as possible and gain a foothold in the city, as the Russian Air Force is not conducting airstrikes against residential areas in the city of Palmyra
Overnight Saturday, the Syrian Army, backed by Russian air strikes, managed to repel several attacks on Palmyra, killing up to 300 jihadists, the Russian Defence Ministry said.
Also on Saturday, terrorists reportedly entered some of Palmyra's districts forcing the Syrian troops to withdraw from some of their positions. According to AP, citing the activist-run Palmyra Coordination network, militants gained footholds in the northern and northwestern districts of Palmyra.
According to the Russian Centre for Reconciliation, the terrorists are also receiving support from militants coming from Iraq.
Earlier [Russian] intelligence spotted a transfer of up to 5,000 Daesh-militants to the areas of Raqqa and Deyr ez Zor from Mosul, Iraq
In October, Russian Foreign Minister Sergey Lavrov warned that terrorists "could flee from Mosul and go to Syria."
Palmyra was seized by Daesh in 2015, however in March this year Syrian government forces, backed by Russian air support, managed to liberate the city.
