Russian investigators have identified Kyrgyz-born Akbarzhon Dzhalilov as the suicide bomber who carried out Monday's deadly attack on a crowded subway train in St. Petersburg.
The country's Investigative Committee says it discovered the burned remains of the man who they believe is behind the attack that killed 14 people and left nearly 50 others injured. The Committee also said investigators found Dzhalilov's DNA on an unexploded bomb planted in another subway station in St. Petersburg on Monday.
Dzhalilov was identified as the bomber earlier in the day by intelligence authorities in Kyrgyzstan, who said he had obtained Russian citizenship, according to "preliminary data."
The explosion Monday was so powerful it blew a hole through the thick metal doors of a subway car.
St. Petersburg authorities shutdown a Metro station at the city's Sennaya Square for several hours Tuesday after receiving a bomb threat. VOA correspondent Daniel Schearf retweeted photos of emergency personnel responding to the threat.
On Monday, Russia's REN-TV showed dead and wounded lying on a station platform, as horrified passengers rushed by, many of them covering their faces to avoid the thick smoke.
Police defused another bomb hidden inside a fire extinguisher at a second St. Petersburg station. The city's entire subway was shut down for much of Monday. Moscow took what it called "additional security measures" on its metro.
Three days of mourning
Officials in St. Petersburg have declared three days of mourning.
President Putin was in St. Petersburg for a meeting with Belarusian President Alexander Lukashenko. Putin brought flowers to the subway station, where a memorial of flowers and candles grows.
President Donald Trump called the blast an "absolutely terrible thing," while a spokesman for U.N. Secretary-General Antonio Guterres said "those responsible for this appalling act must be held accountable."
A terrorist attack would be quite serious, says the director general of the Russian International Affairs Council, Andrei Kortunov. "Because we have not experienced anything like that for a long period of time in Russia. And, definitely, we are back to where we were some 10 or 12 years ago when these explosions unfortunately took place on a more or less regular basis," he said.
The last subway attack was in Moscow in 2010, when female suicide bombers connected to an Islamist insurgency in Chechnya were blamed for killing at least 33 people. Earlier bombings on the Moscow metro in 2004, also linked to Chechen terrorists, killed nearly 50 people.
"Obviously, the North Caucasus is still a mess and there is always the sort of risk of terrorist attacks emanating from there," said Mark Galeotti of the Institute of International Relations in Prague, speaking via Skype. "But certainly the Federal Security Services' own assessments are, what they are particularly concerned about, is exactly some kind of connection with fighters, Russian fighters, who have joined Islamic State. What happens when they return? So, it could be that."
It would be the first time in recent memory that such an attack happened in Russia's second-largest city.
"Somehow, St. Petersburg was lucky to avoid such things," said Kortunov. "Of course, terrorists usually target the capital because it might give them high exposure. So, it sets a precedent."
Added Galeotti: "This could be the start of a trend or it could be a one-off. I think the key thing is, given that we will now probably see quite a stepping up of security in the short-term, if there are still more attacks, then I think this does spell exactly what the security services have been worried about, which is actually a resurgence of terrorism. If it's just a one-off attack, though, probably things will quite quickly get back to normal."
Unlike previous incidents of suspected terrorism, Russian state media were quick to report details of the blast in St. Petersburg.
"They learned a lesson, which is precisely by not covering stories all they end up doing is actually as it were, handing the narrative to rumor, gossip and Twitter," said Galeotti. "By actually reporting quickly and reporting fairly and honestly, actually what they do is they slightly tamp down potential panic and they sort of make sure that people are not automatically assuming that they're not being told most of the story."
Regarding Putin’s presence in the area, Kortunov said, "Definitely, it could be connected because his presence there got a lot of media coverage. And, I think that though terrorists cannot target the president directly, but it is clearly a message for the president of the Russian Federation if it, indeed, was a terrorist attack."
Putin and Lukashenko expressed condolences to the relatives of the victims.
"Certainly, all causes are being considered, both common crime and manifestations of terrorism," Putin said as the two men met. "The investigation will soon provide all answers to what has happened."
