On a recent Tuesday, drone strikes targeted two commercial vessels approximately 80 miles off the Bulgarian coastline in the Black Sea. The attacks resulted in the sinking of the Togolese-flagged Alfa Watan and significant damage to the Palau-flagged Able.

The sinking of the Alfa Watan and the Able

The drone strikes, which occurred within Bulgaria's exclusive economic zone,utilized a combination of maritime and aerial drones to strike the vessels. According to the report, the impact on the ships was catastrophic, leading to immediate structural failure.

The details of the maritime incidents are as follows:

  • The Alfa Watan: Flying the flag of Togo , this vessel sustained severe damage and sank almost instantly. Vice Admiral Rumen Nikolov reported that the explosion was so powerful that the ship disappeared beneath the waves, leaving no survivors or bodies to be recovered.
  • The Able: Sailing under the flag of Palau, this ship was set ablaze by the sttrike. Fortunately, a Bulgarian ferry was able to rescue all 18 crew members from the vessel.

A surge from 59 to over 200 hybrid attacks

These maritime strikes are part of a frighteningly rapid escalation in regional instability. Data from an Associated Press interactive map, cited in the report, shows that hybrid attack incidents have climbed from 59 in March 2025 to more than 200 at the current time. This trend suggests that the Black Sea is becoming a primary theater for hybrid warfare, where attackers use methods that allow for plausible deniability.

This pattern of aggression is not isolated to Bulgaria. As the report suggests, these incidents follow a similar pattern to a previous attack on a Turkish-owned cargo ship carrying corn, which also resulted in a sinking and fatalities. Such tactics are increasingly viewed as attempts to destabilize sovereign nations and test the readiness of military alliances like NATO.

President Yotova’s emergency security council response

In response to the crisis, Bulgarian President Iliana Yotova convened an emergency session of the national Security Council to assess risks to critical infrastructure and maritime security. President Yotova condemned the strikes as a blatant violation of international law and called for an immediate investigation into the perpetrators.

To assist in the analysis of these attacks, the European Commission has stepped in to provide Bulgaria and Romania with critical satellite imagery.. President Yotova has explicitly linked the deteriorating security environment in the Black Sea to the broader ongoing conflict between Russia and Ukraine.

The clash between Zelenskyy and the Russian Embassy

The identity of the attackers remains the central unanswered question of this maritime crisis. While Ukrainian President Volodymyr Zelenskyy has explicitly blamed Russia for the drone strikes,the Russian Embassy in Sofia has issued a categorical denial. The Russian Embassy stated that the vessels were not targets of their armed forces and urged stakeholders to wait for the final investigative results.

As the official investigation continues, several specific points remain unverified. It is still unknown whether the drones were launched from state-controlled platforms or independent actors, and the exact origin of the maritime drones used in the strike on the Alfa Watan has yet to be confirmed by Bulgarian authorities.
