Darya Shipavheva, a Russian journalist, has been convicted of treason by a Moscow court and sentenced to 12 years in a penal colony on Wednesday, the Interfax news agency reported.
The trial was held behind closed doors and no details of the case were officially released.
Interfax, citing other media, reported that the charges stemmed from an alleged money transfer to Ukraine.
Shipacheva pleaded guilty and received the minimum sentence for the offence.
In a short video posted by independent news outlet Mediazona from inside the courtroom, she looked shocked as the verdict was announced.
According to Mediazona, she specialised in science and medical journalism and worked for several prominent Russian media organisations.
Russia has tightened censorship laws and increased pressure on independent media since launching its war in Ukraine in 2022.
Prior to the verdict, the Committee to Protect Journalists, an independent non-profit organisation that promotes press freedom worldwide, said 29 journalists were imprisoned in Russia in connection with their work.
