A Turkish cargo ship suffered minor damage from a mine 20 kilometers from the Romanian port of Sulina on the Black Sea, British maritime security company Ambrey reported on Oct. 5.
The crew was unharmed and the damage was slight enough that the ship could resume its voyage. An unnamed Ukrainian source quoted by Reuters confirmed that the ship had struck a mine, commenting that it was "probably a World War II mine, or the landing mines that were left there last year."
Russia unilaterally exited the Black Sea Grain Initiative on July 17, effectively ending the safe passage of cargo ships through the Black Sea. As a result, Ukraine opened a humanitarian corridor near the Romanian and Bulgarian coasts that would allow cargo ships to continue to transit through the Black Sea.
The route is not without risk to those who use it. The Russian Defense Ministry has said that all vessels sailing to Ukrainian ports would be considered "potential carriers of military cargo" and, therefore, legitimate targets.
On Oct. 4, British intelligence issued a report cautioning that Russia may use sea mines to target civilian cargo ships in the Black Sea, and then blame Ukraine after the fact.
In addition to the garbage, debris, and dead animals resulting from the dam explosion, floating mines and ammunition also littered the water.
