Operation Rainbow was an operation launched by the Syrian Army, supported by Hezbollah and other allied militias, during the Syrian Civil War, following a successful operation which led to the military encircling Aleppo from the east side and reaching the city's northern approach. The aim of the operation, as the previous one, was to encircle Aleppo and cut rebel supply lines into the city, thus besieging rebel-held areas.
