Earlier this week Kremlin-backed Syrian dictator Bashar al-Assad effectively won the battle of Aleppo, with rebels fleeing their last major urban stronghold.
Assad and Russia offered a “safe corridor” to militants and civilians leaving Aleppo. The agreement was immediately disrupted by pro-Assad Shia militias who fired on a Red Crescent ambulance, according to pro-rebel media.
In 2014 the Kremlin proposed a similar “safe corridor” to Ukrainian soldiers leaving the city of Ilovaisk in Donetsk Oblast. Later hundreds of those soldiers were massacred by Russian regular troops.
