WASHINGTON: Ukraine’s ambassador to the United States was quoted as saying on Friday that Ukrainian nationals were among members of the crew of the Russian-flagged tanker Bella-1, seized this week by US forces. Olha Stefanishyna, quoted by the Interfax Ukraine news agency, said Ukrainian diplomats were in contact with US authorities to ensure consular access to the crew members. “The embassy has the situation under control and is using all necessary means to maintain contact with the Ukrainian citizens,” Stefanishyna was quoted as saying.
