At least 10 people have been killed in an explosion between two underground stations in St Petersburg.

The head of Russia's National Anti-Terrorist Committee said the blast hit the train between Sennaya Ploschad and Tekhnologichesky Institut stations.

Images posted on social media showed a badly mangled carriage, with a number of casualties nearby.

President Vladimir Putin said all causes, including terrorism, were being investigated.

Initial reports suggested there had been two explosions, one at each of the two stations.

At least 50 people have been reported injured, and a number of children were among those hurt.

Andrei Przhezdomsky, the head of the Russian National Anti-Terrorist Committee, said it was caused by "an unidentified explosive device" but that the exact cause had yet to be determined.

However, a spokesman for Russia's prosecutor general said the explosion was "a terrorist act".

President Putin was in St Petersburg earlier on Monday but is now outside the city, his spokesman Dmitry Peskov said.

"I have already spoken to the head of our special services, they are working to ascertain the cause," he said, at a meeting with Belarus President Alexander Lukashenko.

The entire St Petersburg underground network has now been shut down, and Moscow metro officials said they were introducing extra security measures as a result.

St Petersburg's metro system is the 19th busiest in the world, with more than two million passengers every day. It has not suffered attacks before.

However, several transport hubs in Russia have been attacked. In 2010 at least 38 people died in a double suicide bombing on the Moscow metro.

In 2009, a bomb exploded on a high speed train travelling between Moscow and St Petersburg, killing 27 and injuring another 130.

Both attacks were claimed by Islamist groups.

Yes. A big set of stations there, in the old hystorical centre. Thanks God it was not evening time - then it will be much more casualties.
Lets hope we'll find those responsible soon.

Just a few days after one of the biggest demonstrations against the government there. Interesting...

Hopefully, they catch the people who were behind that and make an example of 'em.

What do you mean by this? Do you think the Kremlin had anything to do with it? I bet we can get at least a major demonstration before every terror attack that occured in the US/EU the past year without even trying.

A terrorist attack is an atrocity no matter where it happened. If it is prooven that way I hope the FSB blows them off the face of the world.

Well then show me these big demonstrations before an attack then since you dont even have to try.

Im not saying the government there had anything to do with it, but it sure came at a suspicious time. They have no suspects, but they seemed to be very quick to call it a terrorist attack.

However terroists are usually idiots, so who knows?

With all their bombings in Syria I'm surprised this hasn't happened sooner. Sadly the world cup next year will probably be a massive target for extremists just like France was for the euros.

Victims of terrorism and unprovoked violence have my utmost sympathy no matter where they are in the world. I really feel for the masses who are attacked just trying to live their everyday life.

Stay strong St. Petersburg.

Here, and this was the search result I came up with in less than 3 minutes. If you want more/country feel free to google it, as there are plenty more, or if you are lazy give me a random terrorist event and I will search it for you. Pretty much every major country last year in the west was mired in massive scale protests often directly against their way leaders handled certain sittuations (see germany, france and currently lets not forget the US). I hate it when people start demonizing a country just because reasons and mainstream media provoked hysteria.

Again, I dont want to derail the thread with politics, and RIP all people who now rest in those metal graves.

Ok, so if I think its a bit suspicious that it happened just after a big demonstration, I am now deomnizing the entire country because of the media? This is why it will always be a one sided debate. Maybe stop attacking people who might have a different opinion than you? Again Im not saying that anything is set in stone, but Im not gonna just say "Hope the guy who did this goes to jail for a million years" and be done with it. Of course its a sad situation and I feel for the families of the victims, but stop saying I have some sort of agenda for thinking differently than you.
