During the night of October 5 to 6, two merchant ships were attacked by drones near the Bulgarian coast, resulting in the disappearance of a dozen seafarers. According to BNT, Bulgaria's public television channel, the incident occurred at 3 a.m., 70 nautical miles (about 130 kilometers) from Varna, a small coastal town in northeastern Bulgaria. The attacks involved both aerial and underwater drones, with one of the ships sinking immediately and the other reported to be in distress. One of the rescued seafarers, speaking to Bulgarian coast guards during the night, suggested that the attack involved a Russian submarine bomb rather than a drone. He said, "I think the Russians launched a submarine bomb, a fire started. It wasn't a drone, it was underwater. I think it was Russian, because we were carrying Ukrainian cargo." The seafarer is part of the crew of the Able, a cargo ship registered in Palau. According to Bulgarian media, all 18 crew members—11 Turks and 7 Indians—were rescued and are now safe. The Able was transporting wheat and was heading south when the attack occurred. The second ship, whose name has not been disclosed, was also struck and is reported to be in distress. The nature of the attack has raised questions about the possible involvement of Russian forces, particularly because the ship was carrying Ukrainian cargo. This has added to the growing concerns about the escalating conflict in the Black Sea region. Bulgarian authorities are currently investigating the incident, and international maritime agencies have been informed of the event. The attack has highlighted the increasing tensions in the Black Sea, a region already affected by the ongoing conflict between Russia and Ukraine. While the exact cause of the attack remains under investigation, several theories are being considered, including the possibility of a military operation or a targeted strike. The incident has drawn international attention and underscores the risks faced by commercial shipping in the area.
