Syrian rebels led by an Islamist militant group have breached Aleppo for the first time since 2016, seizing towns and villages along the way. The ongoing offensive has resulted in the deaths of 27 civilians, including eight children. Insurgents have used car bombs and clashed with government forces on the city's western edge. Witnesses report missiles and exchanges of fire prompting residents to flee their neighbourhoods. The Syrian government has not commented on the breach.
