"The command of the Black Sea Fleet has issued a warning to mariners about the presence of a mine hazard on the shipping route in the northwestern part of the Black Sea. The warning to mariners is due to the discovery of a Ukrainian sea mine, which drifted uncontrollably, endangering the safe navigation of civilian ships," the ministry said in a statement.
The sea mine that was found was set by Ukrainian naval forces in early 2022 during indiscriminate mining of coastal waters, the ministry added.
"The unprofessionalism and irresponsibility of the Ukrainian navy has led to the fact that today an unknown number of mines are drifting in the Black Sea, posing a constant threat to shipping," the ministry said.
