"Russian propagandist Anna Kurbatova will be forcibly returned to the Russian Federation," SBU spokeswoman Olena Gitlianska wrote on Facebook on Wednesday afternoon.

Channel One earlier reported that SBU employees had detained its journalist Anna Kurbatova in Kyiv.

Kurbatova was included in the database of the Ukrainian Myrotvorets (Peacemaker) website, which tracks separatists and war criminals, because of her anti-Ukrainian activity. In particular, she was engaged in the production of a biased news story about a Ukrainian military parade on Independence Day by distorting and manipulating facts.
