Four ships have been attacked in a week in Bulgaria's exclusive economic zone in the Black Sea, and two of them sank, prime minister Rumen Radev told parliament.

This report follows our earlier story on the new drone attacks on ships in the Black Sea. After those attacks, Democratic Bulgaria asked the government to take five steps, and the prime minister called the attacks absolutely unacceptable.

The strikes came on 6 and 13 October, in the dark. On 13 October the sea was rough, visibility was poor, clouds were low and it was raining.

Four people were rescued from one of the two sunken ships. No one was rescued from the other. The other two ships are still afloat, and all their crew members have been rescued.

"We showed that Bulgaria can act quickly and on time, and that it can control its exclusive economic zone," Radev said. He added that Bulgaria also ran search and rescue operations, in line with its duties under international conventions.

The prime minister thanked the Air Force, the Border Police, the Maritime Rescue Centre in Varna and the Maritime Administration for "extremely timely, professional and responsible action" in rescuing the sailors. He said the teams did the job well despite the conditions.

MPs questioned the prime minister about the action taken, the risk assessment and the steps ahead. They also asked about reports that Starlink satellite antennas were set on fire on purpose.
