A man has been sentenced to four-and-a-half years in prison in Ukraine for plotting to kill exiled Russian journalist Arkady Babchenko, Ukraine’s state security agency says.
Borys Herman is said to have pleaded guilty and agreed to co-operate with the investigation.
He was accused of acting as the middleman between alleged contacts in Russia and a hired assassin in Kiev.
Mr Babchenko escaped by faking his own death.
He was helped by the man hired to kill him and Ukraine’s security services.
To widespread astonishment, the 41 year old appeared the day after his murder was reported to admit it had all been staged.
Relations between Kiev and Moscow are tense with Russia having illegally annexed Crimea in 2014 and continuing to support armed rebel groups in Ukraine’s east.
The man hired to assassinate Mr Babchenko says he played along to help authorities gather more information.
Oleksiy Tsymbaliuk, a former Ukrainian Orthodox priest, told the BBC earlier this year that he had alerted security services as soon as Mr Herman, a fellow Ukrainian, asked him to kill Mr Babchenko.
Mr Herman did not deny plotting with Mr Tsymbaliuk, but initially said he was also working with Ukraine’s SBU security services and knew all along that the assassination would be faked.
