A former sushi chef and martial arts buff was identified Tuesday as a Kyrgyz-born suicide bomber who killed 14 people and wounded dozens of others on a St. Petersburg subway car, authorities said.

Akbarzhon Jalilov, a Russian citizen who turned 22 two days before the attack, had ties to radical Islamists, according to law enforcement officials – raising the possibility the attack could have been inspired by ISIS, Reuters reported.

The Kyrgyz GKNB security service said Jalilov was born in Osh – the second-largest city in the former Soviet state in Central Asia – and had lived in Russia for six years.

Investigators said the backpack bomb that exploded near the Sennaya Ploshchad station “could have been activated by a man whose fragmented remains were discovered in the third carriage,” Agence France-Presse reported.

Russia’s investigative committee said Jalil’s DNA had been found on an unexploded device left at a second metro station, the Ploshchad Vosstaniya, The Guardian of the UK reported.

The Russian Interfax news agency said the second bomb – a shrapnel-filled fire extinguisher — would have been several times more powerful than the first.

The forensic evident and surveillance footage led authorities to believe the same person was responsible for both bombs, officials said.

There has been no claim of responsibility for the Monday afternoon blast, which came while President Vladimir Putin was visiting his hometown city.

Meanwhile, Russia’s Health Minister Veronika Skvortsova said Tuesday that the death toll had risen to 14, with at least 50 wounded. Eleven people died at the scene, one died on an ambulance and two more died in a hospital, she said.

The naming of the suspect followed 24 hours of unsubstantiated rumors about his identity.

A Kazakh man named by some news outlets as a potential suspect overnight was apparently one of the victims, while a man whose photograph was widely circulated by Russian media Monday later went to police to state his innocence.

Putin received a phone call from President Trump early Tuesday.

“President Trump offered the full support of the United States government in responding to the attack and bringing those responsible to justice,” a White House statement said. “Trump and President Putin agreed that terrorism must be decisively and quickly defeated.”

On Tuesday, the driver of the targeted train told Russian media how he decided to continue on to the next station – the Tekhnologicheskii Institut – after the blast to make evacuation easier.

“There was a bang, and dust. I made contact with the controller and explained the situation,” Alexander Kaverin said, The Guardian reported.

“Then I started getting incomprehensible messages on the intercom system, from all the carriages at once. I made the decision according to the rules for such emergencies, to continue on to the next station,” he said.

Witnesses on the crowded train said it was shaken by a “thundering clap” that filled the car with smoke shortly after it left the station, the Telegraph of the UK reported.

“We all moved to the opposite end of the wagon, people jammed together and two women passed out. This all was happening while the train was still moving, it didn’t stop,” Polina, a student, told Gazeta.ru.

St. Petersburg was last struck by terrorism in October 2015, when a bomb on board a Russian airliner traveling from Egypt’s Sinai peninsula killed 224 people, many of them tourists from the city.

An affiliate of ISIS claimed responsibility for the tragedy, calling it revenge for Russia’s military intervention in Syria.

Russian officials said they were treating Monday’s attack as an act of terrorism, but there was no official confirmation of any link to Islamist radicals.

Foreign Minister Sergei Lavrov said it was cynical to say the bombing was revenge for Russia’s role in Syria. He said the attack showed that Moscow needed to forge ahead in its fight against global terrorism.
