Russia's Investigative Committee on Tuesday named the attacker behind Saint Petersburg metro blast as Akbarjon Djalilov, adding that he had also planted a second bomb that was defused by the authorities.
"The investigation identified the man who set off the bomb in the carriage of the Saint Petersburg metro. It was Akbarjon Djalilov," a statement by the committee said, adding that Djalilov's "genetic trace" was also found on a bag with the second bomb found at a different station.

Earlier, security services in Kyrgyzstan had said a suicide bomber from the central Asian country was behind the explosion that killed 14 people and injured dozens more.
"The suicide bomber in the Saint Petersburg metro was a Kyrgyz national Akbarjon Djalilov... born in 1995," a spokesman for the country's security services had told AFP.
"It is probable that he acquired Russian nationality," he said.
There has been no official confirmation or claim of responsibility.
The suspect had radical Islamist links, Russian media cited law enforcement officials as saying, raising the possibility Monday's attack could have been inspired by Islamic State, which has not struck a major city in Russia before.
Biographical details pieced together from social media and Russian officials suggested Jalilov was an fairly typical young St Petersburg resident with an interest in Islam as well as pop music and martial arts but no obvious links to militants.
His uncle, Eminzhon Jalilov, told Reuters by telephone that his nephew was a mosque-attending Muslim, but that he was "not a fanatic".
