Ukraine accuses Russia of violating a UN maritime treaty by building a bridge in the Sea of Azov and Kerch Strait.

Ukraine has accused Russia of attempting to illegally control the Sea of Azov and Kerch Strait during arbitration hearings at the Permanent Court of Arbitration, related to Russia's annexation of Crimea and its 2022 invasion. Ukraine claims Russia violated a UN maritime treaty by building a bridge that restricts fishing and damages the environment. Russia denies jurisdiction and argues the waters are "internal." A final ruling may take years.
