The suspected suicide bomber has been named as 22-year-old Akbarjon Djalilov, who is thought to have been a Russian national born in Kyrgyzstan.
"[He] carried out training of the suicide bomber terrorist Djalilov," the FSB said, calling him "one of the organizers."
Djalilov is suspected of triggering a homemade explosive device while on a train in a metro tunnel.
Security forces said they safely defused another device left on a platform.

Eight others - detained in Moscow and St. Petersburg in connection with the attack - are also from Central Asia.
