EXECUTIVE SUMMARY
A commercial ship sank in NATO waters off Bulgaria following a combined Russian aerial and maritime drone strike.
A commercial ship sank and its crew vanished Tuesday after an apparent coordinated air-and-sea drone attack off NATO member Bulgaria, as Ukrainian President Volodymyr Zelenskyy blamed Russia before warning Moscow was preparing a broader "massive strike."
A second vessel was also heavily damaged and set ablaze inside Bulgaria’s exclusive economic zone, with a drone expert warning the dual precision strikes signaled a dangerous escalation and possible "larger invasion posture" by Russia.
