Syrian rebel groups have made a surprise advance against the Syrian regime near Aleppo, causing the largest setback for the regime and its Iranian backers in years. Videos show Hayat Tahrir al-Sham inside a Syrian regime base. The rebel groups are attempting to restart fighting with the regime, following days of strikes by the regime against areas in Idlib. Turkey's control of rebel groups has limited their independence, leaving HTS and affiliated groups as the only ones capable of conducting independent operations. The attack on the Syrian regime comes after the ceasefire between Israel and Hezbollah, catching the regime off guard.
