CCTV footage of the incident on 10 July – verified by the news agency Reuters – showed a man leaving a building in Kyiv’s southern Holosiivskyi district shortly after 09:00 local time (06:00 GMT), while another man ran towards him.
The SBU said on Sunday the suspects had been tracking Col Voronych’s movements prior to the attack, and were sent the co-ordinates of a hiding place where they found a pistol with a silencer.
It said that after he was shot, they then tried to “lay low,” but were found following a joint investigation with national police.
The SBU mainly focuses on internal security and counter-intelligence, like the UK’s MI5. But it has played a prominent role in sabotage attacks and assassinations deep inside Russia since Moscow’s full-scale invasion of Ukraine in 2022.
Sources within Ukraine’s security services told the BBC that the SBU was responsible for the killing of the high-ranking Russian Gen Igor Kirillov in December 2024.
In April, Gen Yaroslav Moskalik was killed in a car bomb attack in Moscow – which the Kremlin blamed on Kyiv.
Ukraine’s security services have never officially admitted responsibility for the deaths.
