Azerbaijan Airlines blames 'external interference' for a plane crash in Russia. The head of Russia's civil aviation agency stated that a closed-skies protocol was put in place due to Ukrainian combat drones launching attacks on civilian infrastructure. Azerbaijan Airlines did not provide specific details of the interference, but aviation experts believe the plane was damaged by shrapnel from a Russian air-defense missile explosion. The airline has suspended flights to several Russian cities for security reasons, and Israel's El Al has also suspended flights to Moscow. Vigils have been held in Azerbaijan to honor the pilots who saved lives by landing part of the plane despite being killed in the crash.
