Different sources report that Al Sukhna, the last ISiS-held town in the eastern Syrian Homs region, has fallen, clearing the way for Syrian troops and allied militias to advance on Deir ez-Zour, where the Islamist State maintains key strongholds. At the same time, the Russian-US-backed ceasefire zone called in Homs last Thursday was repeatedly broken since then by the Syrian government and rebel forces.
