Leonid Slutsky, the chairman of the International Affairs Committee of the State Duma of Russia, described the confiscation of the Marinera ship by the USA as "21st-century piracy."

The Russian Ministry of Foreign Affairs has requested the release of the Russian citizens on board, emphasizing that the U.S. action violates maritime law. Leonid Slutsky accused the U.S. of acting on the basis of "the law of force" and demanded humane treatment for the Russian citizens. The ship, sanctioned by the U.S. in 2024 for illegal activities, was seized with British support. The White House announced that the crew could be prosecuted in the U.S. for violations of federal law, and the spokesperson stated that President Trump is not afraid of escalating tensions with Russia. It is also mentioned that Russia may have sent a submarine to protect the seized ship.
