Two separate vessels were hit by drone strikes in the Black Sea off the Bulgarian coast, leading to a maritime emergency. According to Bulgarian Prime Minister Rumen Radev, one of the ships sank following the attack, while the other sustained significant damage. Rescue operations were launched immediately, resulting in the rescue of one individual from the sunken ship and 15 crew members from the second vessel, identified by Al Jazeera as the Chelsea 3.

There is currently a discrepancy regarding the origin of the drones. While reports indicate that the source of the strikes remains unknown, the incident has prompted a strong diplomatic response. Prime Minister Radev described the attacks as "absolutely unacceptable" and announced his intention to request assistance from NATO and the European Union to address the security threat.

This incident follows a similar event that occurred one week prior, where another ship was sunk and a second vessel was evacuated, resulting in 18 rescues. The recurring nature of these attacks in the Black Sea has raised concerns regarding maritime security in the region. While Al Jazeera specifically identified one of the vessels as the Ukrainian-owned Chelsea 3, The Guardian focused more broadly on the rescue statistics and the Prime Minister's call for international intervention. The investigation into the identity of the attackers is ongoing, with no group or state actor currently claiming responsibility for the strikes.
