Russia’s Federal Security Service (FSB) said on Monday that the attempted assassination of General Vladimir Alexeyev was ordered by the Security Service of Ukraine (SBU), the Interfax news agency reported.

The FSB said that Polish intelligence had been involved in the recruitment of the shooter.

The FSB did not provide any evidence that Reuters was able to immediately verify.

A Ukrainian-born Russian citizen has been extradited to Moscow from Dubai on suspicion of gravely injuring Alexeyev, Russian security officials said on Sunday.
