A Ukrainian naval drone exploded at Constanța, Romania's largest Black Sea port, on the morning of June 5, causing full evacuation but no reported casualties. The device, identified as a MAGURA-type drone similar to those used by Ukraine's armed forces, detonated near an oil terminal after becoming lodged in anti-pollution containment. Romanian authorities subsequently discovered four additional unmanned vessels in the coastal zone, marking the latest in a series of incidents involving Ukrainian weapons crossing into NATO territory.
