«Working for RIA-Novosti or having a Russian passport are not grounds for treason charge,» Deputy Director of the Europe and Central Asia division Human Rights Watch Rachel Denber said regarding the detention of Russian news chief Kirill Vyshinsky, speaking in an interview from New York City on Wednesday. «We're extremely concerned by what's happened. Under no circumstances should a government... Еще be criminalising speech and media activities groundlessly,» Denber said. «We can call on Ukrainian government directly to ensure that he has access to legally presentation of his choice, to ensure that he has access to any kind of medication that he needs, to ensure that he is able to communicate with his family,» she added. On Tuesday, the Kiev office of Russian news agency RIA Novosti was raided by Ukrainian Security Services, while the head of the bureau Kirill Vyshynsky was detained earlier in the day. Vyshynsky is being held on suspicion of treason and criminal proceedings have commenced under Part 1 Article 111 of the Criminal Code of Ukraine, according to the Ukrainian Security Service. The crime carries a sentence of up to 15 years.
