Reporters Without Borders (RSF) has expressed concern about the detention of Kirill Vyshinsky, who heads RIA Novosti Ukraine, by the Kiev security services. The international NGO said in a statement that it is “worried about the arrest” and called on the Ukrainian authorities to “either precisely explain how the alleged actions [of the journalist] constituted high treason or release Kirill Vyshinsky without delay.” It also said that “the charge of high treason and pre-trial detention are extremely serious measures.”
