The St. Petersburg metro attack was carried out by a suicide bomber, the Kyrgyz Foreign Minister has said.

Kyrgyz authorities had earlier identified Akbarjon Djalilov, a Russian national born in Kyrgyzstan, as a suspect in the blast that ripped through a train in Russia’s second city on Monday afternoon.

The Russian health ministry raised the number of dead from 11 to 14, although it was unclear whether that included the attacker. Four of the dozens of people injured are in critical condition, Health Minister Veronika Skvortsova said, according to TASS.

Russians laid flowers and tributes at memorials and a three-day period of mourning has begun.

The explosion took place between the Sennaya Ploshchad and Tekhnologichesky Institut stations at about 2.40 p.m. on Monday. Photographs from the scene showed bandaged and bloodied bodies being carried from the station where the train came to a stop.

Others showed bodies lying by the train itself at Tekhnologichesky Institut as the station filled with smoke.

A second, larger device was found and defused at another station, Russia’s Anti-Terrorism Committee said.

That device, hidden in a fire extinguisher, was larger than the one that exploded, according to state media reports that quoted law enforcement sources. It carried about a kilogram of TNT, the reports said.
