Damascus-led forces “will need to cross the Euphrates in order to advance towards Raqqa. The US-backed SDF are active on the bank the SAA moved to. The Kurds have reached the left bank of the Euphrates, south of Raqqa. In other words, they have cut the direct route between the city and Deir ez-Zor. Government forces need to reach an agreement with the SDF if they want to move towards Raqqa,” he explained, adding that it is highly unlikely that both sides will ink such a deal.
