A Russian citizen of Kyrgyz origin was identified as the perpetrator of the terror attack that left 14 dead on the St. Petersburg metro, Russian authorities announced on Tuesday.

The spokeswoman for the chief Russian investigators, Svetlana Petrenko, said the assailant was identified as Akbarzhon Jalilov using genetic analysis and security camera footage of Monday's attack.

She said criminal investigators found traces of his DNA on the explosive suitcase that had been left behind in the Ploschad Vosstania station, which was deactivated by police before it could be detonated.

On Monday, Jalilov allegedly detonated an explosive on the St. Petersburg metro between the central Sennaya Square and Tekhnologichesky Institut stations.

The blast killed at least 14 people and left over 50 injured.

The Kyrgyz and Russian foreign ministers, Erlan Abdyldaev and Sergey Lavrov respectively, met Tuesday in Moscow to discuss the attack.

Abdyldaev said it could not yet be determined whether or not the assailant was a member of the Islamic State terror organization.

The 22-year-old Jalilov, who worked at a garage in St. Petersburg, was born in Osh, Kyrgyzstan, but obtained Russian nationality in 2011.

To prevent further attacks, Russian authorities have reinforced security measures across St. Petersburg and Moscow at public transport stations, public buildings, squares, schools and kindergartens.
