Summary

Two merchant vessels were reportedly hit by drones in Bulgaria's Black Sea exclusive economic zone near the coast, around Byala, during darkness. Ukrainian Foreign Minister Andrii Sybiha, Bulgarian officials and a sailor aboard the Chelsea 3 attribute the attacks to drones, and Bulgarian authorities suspect Russia, while Moscow denies involvement and Prime Minister Rumen Radev has not confirmed the claims. Reports differ on the outcome: one vessel, the Guinea-Bissau-flagged HS Dignity, was reported to have sunk, with five people rescued and 11 still missing according to some accounts, but later reports do not confirm those figures for this incident. The Maltese-flagged Chelsea 3, Ukrainian-owned, was towed to Bourgas with hull damage, and six people aboard were injured. Bulgaria has sought NATO and EU assistance and analysis of drone debris found on the Chelsea 3.
