Missed shot in Baltic Sea maneuver: Russia's navy accidentally sinks its own fishing trawler. In Belgorod, Russia, a Russian fighter jet accidentally fired a missile at the border with Ukraine in April last year.

And in February of this year, the Russian news channel Astra reported that a fighter jet had “unplanned ammunition firing” at the city of Astra. There are now increasing signs that a Russian missed shot could have caused the explosion on board the fishing boat Kapitan Lobanow.
