A Russian ship captain has been detained in Sweden on suspicion of using forged documents to evade Western sanctions. The tanker, Sea Owl One, was intercepted by the Swedish coast guard while sailing under a potentially false Comoran flag. The vessel, which has transported oil between Russia and Brazil, is on a list of EU-sanctioned ships, and its captain is being held for further questioning. The detention is part of a broader effort to crack down on Moscow's shadow fleet, which has been accused of dodging sanctions and engaging in other illicit activities. The incident marks the second time in a week that Swedish authorities have seized a vessel suspected of being part of Russia's shadow fleet.
