A San Marino-flagged oil tanker, the Wine Trader, was struck by drones off Romania's coast on Thursday morning, leaving it ablaze and 8 of 12 crew members missing, Romanian authorities confirmed. The incident occurred 13 nautical miles east of the Danube mouth. Following a spate of recent drone attacks in the Black Sea region, the leaders of Romania and Bulgaria are set to discuss invoking Article 4 of the NATO treaty, which allows members to request consultations if their security is threatened.
