The Russian-installed governor of the Crimean city of Sevastopol said on Saturday that air defences had shot down a drone in what he suggested was the latest attempted Ukrainian attack on a port where Russia's Black Sea Fleet is based.
Mikhail Razvozhaev, the Russian-backed governor of the city, made the allegation on the Telegram messaging service, alleging that the incident had occurred in the early hours of Jan. 7, which is Orthodox Christmas.
