Russia has declared another 10-hour humanitarian truce starting Friday in the war-ravaged Syrian city of Aleppo.

The Russian Defense Ministry says the truce will last from 9 am to 7 pm local time.  A statement by the chief of Russia's General Staff Valery Gerasimov says the decision aims to "prevent senseless casualties".  Civilians and armed combatants will be allowed to quit rebel-held eastern Aleppo. 

Gerasimov says eight corridors -- six for civilians and two for fighters -- could be used. Earlier, Russia and Syrian government had a three-day humanitarian truce, but only very few militants left.
