Answer: Sea of Azov and Black Sea
Notes: Ukraine recently claimed to have attacked the Kerch Strait Bridge, also known as the Crimean Bridge, using underwater explosives. The Kerch Bridge, opened in 2018, is both a road and rail link connecting Russia to Crimea across the Kerch Strait. The Kerch Strait is a narrow waterway that links the Sea of Azov with the Black Sea and is around 4 kilometers wide at its narrowest point. It is an important shipping route and strategic access point.
