Three U.S. diplomats have been removed from a train and briefly questioned by Russian authorities in the sensitive Arctic shipyard city of Severodvinsk, near the site of a mysterious explosion in August that killed five nuclear workers.
Russia's Interfax news agency reported on October 16 that the diplomats were taken off the train that runs between Severodvinsk and Nyonoksa around 6 p.m. on October 14.
At the end of September, the Department of State announced that it would recall half of its diplomatic personnel from the U.S. Embassy in Cuba following the sickening of 21 employees by “specific attacks.” A mysterious sonic weapon had left at least 10 American diplomats with injuries from hearing loss to brain trauma and nervous-system damage. Just weeks before, Secretary of State Rex Tillerson had stated he was evaluating whether to shutter the embassy altogether amid the continued incidents.
