St Petersburg blast: Pranab Mukherjee writes to President of Russia

President Vladimir Putin, who was in the city when the blast occurred, visited the scene on Monday evening and laid flowers at a makeshift shrine.

News agency Interfax, citing a law enforcement source, said alleged links with the suicide bomber who killed at least 14 people on the city's Metro were being checked. "It was Akbarjon Djalilov", a statement by the Investigative Committee said.

His name was later confirmed by Russian investigators, who said he also planted a second bomb that did not explode.

Earlier, Kyrgyzstan's State Committee for National Security identified a suspect as Kyrgyz-born Russian Akbarzhon Dzhalilov.

Health Minister Veronika Skvortsova said the toll from the blast had climbed from 11 to 14 Tuesday as three people succumbed to their injuries, adding that 49 more people remained in hospital.

However, former Federal Bureau of Investigation special agent Bobby Chacon says that to stay silent after an attack goes against the ISIS modus operandi. I made the decision to take the train to the station, because the train kept rolling on normally. On Jan. 24, 2011, a suicide bomber hit Moscow's Domodedovo Airport, killing 37 people and wounding 180.

While Moscow and many other Russian cities have seen numerous attacks linked to Islamic militants, the city of imperial palaces and world-famous art museums largely had escaped such violence until Monday.

"On behalf of the government of Israel, I send condolences to President Putin and to the families of those who were murdered, following today's bombing on the St. Petersburg subway", Netanyahu said in a statement.

A colleague who worked with Dzhalilov for three months in 2013 at Sushi WOK, one of the biggest sushi delivery services in Russian Federation, told RT that he hadn't noticed any suspicious signs about his former co-worker.

Senior investigator Svetlana Petrenko told Russian media the train driver's decision to continue to the next station, Tekhnologichesky Institut, had nearly certainly helped save lives, as it allowed people to be rescued quickly. The attack was carried out by a suicide bomber, but the bomber's intentions are still unclear.

"I had no time to think about fear at that moment", he said.

There was no immediate claim of responsibility for the blast.

Another possibility, says former CNN Moscow Bureau Chief and Woodrow Wilson Center Global Fellow Jill Dougherty, is a hybrid Chechen rebel-ISIS attack.

Islamist militants have targeted Russian Federation many times before but Monday's bombing of a metro train in St Petersburg was, for President Vladimir Putin, personal: it happened in his native city on a day he was making a visit back home.

Russian transport facilities have been the target of previous terror attacks.

The entire subway system in St Petersburg, a city of five million, was shut down and evacuated before partial service resumed six hours later.
