Russia, one of Assad's key allies, has promised Damascus additional military aid to disrupt the Islamists, two military sources said, adding that the new equipment would arrive in the next 72 hours. The Syrian army has been ordered to carry out a "safe withdrawal" from key areas of the city where the Islamists have invaded.
Earlier, it became known that the pro-Turkish Islamist groups fighting against Bashar al-Assad's government forces launched a surprise attack in northwestern Syria.
