Ukraine has repeatedly committed acts of terror against Russian citizens, Russian President Vladimir Putin said Thursday about the murder of a high-profile Russian general in Moscow.

Lt. Gen. Kirillov, who was the chief of Russia's Nuclear, Biological and Chemical Protection Troops, was killed outside his apartment building Tuesday along with his assistant when a bomb attached to an electric scooter went off.

"This murder was committed in a way that is dangerous to the lives of many. The regime in Kyiv has repeatedly committed such crimes, terrorist crimes, terrorist attacks against many citizens of the Russian Federation," Putin said.

Russia said Wednesday it had detained an Uzbek man who had confessed to planting and detonating a bomb which killed Kirillov in Moscow on the instructions of Ukraine's SBU security service.
