An air strike hit relief trucks near the city of Aleppo, killing at least one aid worker and around 20 civilians, and destroying a warehouse and hospital. The Red Cross said at least 20 people were killed in the attack on trucks carrying desperately needed humanitarian relief to thousands of Syrians. “The air forces of Russia and Syria did not conduct any strikes against the UN aid convoy in the southwestern outskirts of Aleppo,” defence ministry spokesman Igor Konashenkov said in a statement carried by Russian news agencies. Konashenkov said the attack the previous night doesn’t appear to have been from an air strike. The Syrian Civil Defence, a volunteer rescue group known as the White Helmets that operates in rebel-held areas, posted images of several vehicles on fire. A video of the attack showed huge balls of fire against the night sky as ambulances arrived on the scene.
