US officials told Buzzfeed News that it suspects Russia may have operated a drone and military aircraft which was used to bomb a hospital treating chemical attack victims.
"Military officials suspect that someone turned off the camera onboard the Russian unmanned drone just before the strike on the hospital Tuesday, effectively turning a blind eye to the attack. The officials did not make clear how the US was able to determine when the drone’s camera was recording."
