An update on the arrest of the RIA Novosti journalist in Kyiv today:
In Vienna, the OSCE representative on freedom of the media raised "serious concern" over the raid, and called on Ukrainian authorities to "refrain from imposing unnecessary limitations on the work of foreign journalists."
"The fight against propaganda must not fall short of international standards and should not represent disproportionate interference in media activities," Harlem Desir said in a statement.
