The facts

  1. The Associated Press counted nine cargo ships and tankers struck by aerial or naval drones near Bulgaria and Romania over 24 days in October and reported at least 30 sailors confirmed dead or reported missing. [1]

  2. CNN reported at least a dozen merchant vessels struck in recent weeks and at least 30 mariners killed or missing; it said some attacks occurred close to or inside Romanian and Bulgarian waters. [2]

  3. Reuters reported on 23 October that Romania blamed Russia for a drone attack that sank a cargo ship, killing one sailor and leaving three missing. That attribution concerns a specific incident. [3]

  4. Bulgaria’s prime minister said on 29 October that expert examinations were under way to establish who carried out the attacks and that the government would respond once drone origins were established. [4]

  5. CNN described the broader wave as Russian attacks; Bulgaria’s official statement and Reuters’ account of Romania’s allegation do not establish a common operator behind every reported strike. [2][3][4]

Still unconfirmed

  • The reports use different periods and vessel counts; the precise number of ships affected across the full series is not reconciled.
  • Whether all reported incidents shared one operator or coordinated command remains unestablished by the sources reviewed.

AP and CNN independently report a substantial cluster of attacks and at least 30 sailors dead or missing, while their ship tallies differ. Reuters and the Bulgarian government provide separate incident-level attribution context. CNN attributes the broader wave to Russia; the article distinguishes that report from Bulgaria’s statement that examinations were continuing and does not assign one operator to every incident.
