The FSB said that the suspect was “guaranteed” a reward of 100,000 dollars and permission to move to the countries of the European Union in exchange for the murder of Kirillov.
They added that he arrived in Moscow on the instructions of Ukraine and received an improvised explosive device.
He installed an explosive device on an electric scooter, which he parked at the entrance of the apartment building where Kirilov lived, the FSB said.
He then rented a car to monitor Kirillov’s residence and installed a camera that broadcast video from the site to his employees in the Ukrainian city of Dnipro.
When they saw Kirilov leave the house, the suspect detonated the bomb, the report said.
