The Russian nuclear-powered submarine Kazan, part of the Russian naval detachment visiting Cuba, arrives at Havana's harbour, June 12, 2024. The Russian nuclear-powered submarine Kazan -- which will not be carrying nuclear weapons -- and three other Russian naval vessels, will dock in the Cuban capital from June 12-17. The unusual deployment of the Russian military so close to the United States -- particularly the powerful submarine -- comes amid major tensions over the war in Ukraine, where the Western-backed government is fighting a Russian invasion.
