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. The SBU said two people – a man and a woman – were suspected of having killed Voronych in a bold daylight attack that was caught on surveillance cameras. It did not say how many suspected FSB agents had been killed on Sunday, but the SBU posted a video in which two bodies were visible. On Sunday, Ukrainian authorities reported that four civilians were killed and 13 others injured in Russian attacks on the Donetsk and Kherson regions since Saturday.
