Russia has arrested a Ukrainian man who is accused of being behind the death of a high-ranking Russian general on Friday.
According to the Russian intelligence service FSB, it concerns a man in his 40s who is claimed to be a Ukrainian agent.
The general was killed by a car bomb in the city of Balashikha, just east of Moscow. The explosion occurred on Friday morning near the general's residence.
Russia accused Ukraine of being behind the explosion already on Friday.
Kyiv has not commented on the incident, but it bears the hallmarks of earlier Ukrainian attacks on key figures within the Russian military.
