Russia strikes second civilian ship in Black Sea in six days, kills both captains

Russia attacked a second civilian vessel in the Black Sea within six days, setting it on fire and killing both captains, as part of an escalating campaign to disrupt the route carrying 90% of Ukraine's farm exports. The attack follows a similar strike days earlier, indicating a deliberate pattern to choke Ukraine's agricultural export corridor. The incident raises risks for shipping insurance and global grain supply, though the full impact on export volumes remains uncertain.
