Syrian opposition forces have launched a major offensive in western Aleppo district, killing at least 89 people and overtaking a military base. The attacks mark a significant escalation in the Syrian conflict, with rebel factions advancing to within six miles of Aleppo and capturing weapons and vehicles. The offensive is believed to be the first major effort by rebel groups to take territory since 2020. The success of the offensive highlights the vulnerability of the Syrian government and the growing strength of the opposition factions.
