Ukrainian President Volodymyr Zelenskyy has accused Russia of attacking two merchant vessels in the exclusive economic zone of Bulgaria on the Black Sea. The ships were reportedly struck by both aerial and maritime drones. One vessel has sunk as a result of the attack, while another has caught fire. The incident raises concerns about the safety of shipping lanes in the Black Sea amid ongoing conflict. This attack follows a withdrawal from the Black Sea Grain Initiative, further escalating tensions in the region. Further investigation is needed to fully ascertain the extent of the damage and confirm the details of the incident, but Zelenskyy directly attributes responsibility to Russia.
