Moscow, Apr 5 (IANS): 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.

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

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, killing at least 14 persons and leaving over 50 injured.

The Kyrgyz and Russian Foreign Ministers met on 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 the Central Asian country of 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.
