The suspect in the killing of top Russian general Igor Kirillov has been charged with an act of terrorism resulting in the death of a person, a notice on the website of the Moscow court said on Thursday.
Russia said on Wednesday it had detained an Uzbek man who had confessed to planting and detonating a bomb in Moscow which killed Kirillov, who was the chief of Russia's Nuclear, Biological and Chemical Protection Troops, on the instructions of Ukraine's SBU security service.
Russia's Investigative Committee, which probes serious crimes, said in a statement on Wednesday that the unnamed suspect identifed as Akhmad Kurbanov had told them he had come to Moscow to carry out an assignment for Ukraine's intelligence services.
In a video published by the Baza news outlet, which is known to have sources in Russian law-enforcement circles, the suspect is seen sitting in a van describing his actions.
He describes placing the device on the electric scooter and parking it outside the apartment block where Kirillov lived.
Investigators cited him as saying he set up a surveillance camera in a hire car which, they said, was watched in the Ukrainian city of Dnipro by people who organized the killing.
The suspect, who is thought to be 29, is shown saying he remotely detonated the device when Kirillov left the building. He says Ukraine had offered him $100,000 and residency in a European country.
Maria Zakharova, a spokeswoman for Russia's Foreign Ministry, said Moscow would raise the assassination at the United Nations Security Council on Dec. 20.
