SBU intelligence agency claims to have ‘liquidated’ members of Russia’s FSB who were suspected of killing Colonel Ivan Voronych last week

Ukrainian intelligence agents killed members of a Russian secret service cell wanted on suspicion of having shot dead a colonel last week, the SBU said.

The SBU intelligence agency said in a statement that the operation had sought the arrest of the agents of Russia’s Federal Security Service (FSB), who it believes were behind the killing of Colonel Ivan Voronych – also a member of the SBU security service – in Kyiv on Thursday.
