Bulgaria accuses Russia of Black Sea drone strikes on two cargo ships; one sinks, 13 injured

Bulgaria has formally blamed Russia for drone attacks on two cargo ships in the Black Sea, one of which sank, injuring at least 13 sailors. This marks a direct state-level accusation against Russia for attacks on commercial shipping, potentially escalating regional tensions and impacting maritime security in the Black Sea. The incident is part of an ongoing pattern of attacks on shipping in the area, but the explicit Bulgarian attribution adds a new diplomatic dimension.
