Two cargo ships, including one Ukrainian-owned, came under drone attack off Bulgaria's coast overnight on October 13, with one vessel sinking and 11 people left missing; Ukrainian and Azerbaijani citizens were among those injured. Bulgarian Prime Minister Rumen Radev said the strikes' outcome 'benefits the Russian Federation' and announced Sofia would summon the Russian ambassador, while oil-covered birds were found along Russia's Black Sea coast following an associated tanker fire, prompting a wildlife rescue appeal.
