Ukraine asked the ECHR to intervene to ensure the well-being of its seafarers detained by the Russian side. In a statement, the court said that in response to the appeal of Kiev, the ECHR asked the Russian government for information about the state of the detained sailors and asked "to provide all relevant documents."

The incident in the Kerch Strait, which led to a new round of aggravation of relations between Russia and Ukraine, occurred on November 25.
