Russia’s security service said on Wednesday that it has detained a suspect in the killing of a senior general in Moscow. The suspect was described as an Uzbek citizen recruited by Ukrainian intelligence services. Russia’s Federal Security Service, or FSB, didn’t name the suspect, but said he was born in 1995.

The FSB said the suspect had been promised a reward of USD 100,000 and permission to move to a European Union country in exchange for killing Kirillov.
