Russia’s top security agency says that it has arrested several suspects accused of involvement in an alleged Ukrainian plot to assassinate senior military officers.

Russian state media says that an Uzbek citizen accused of acting on behalf of Ukraine has been charged by Russian authorities with this week’s assassination of a senior Russian general and his assistant.

Russia's Federal Security Service said on Thursday it had foiled several plots by Ukrainian intelligence services to kill high-ranking Russian officers and their families in Moscow using bombs disguised as power banks or document folders.
