Sean Spicer has the toughest job in Washington

An explosion ripped through a subway train in the Russian city of St. Petersburg on Monday, killing at least 10 people and injuring 50 others, the city's governor told Russian television.

Within two hours, Russian Federation authorities found and deactivated another bomb at a separate busy St. Petersburg subway station, Vosstaniya Square by the Moscow railway station, Russia's National Anti-Terrorist Committee said.

Asked about the report, Putin spokesman Dmitry Peskov wouldn't comment, saying it's up to law enforcement agencies to comment on details of the probe.

The St. Petersburg subway immediately shut down all of its stations and the national anti-terrorism body said security measures would be tightened all key transport facilities across Russian Federation.

Within two hours of the blast, Russian authorities had found and deactivated another bomb at a separate busy St Petersburg subway station, Vosstaniya Square, the anti-terror agency said. He offered his condolences to the families of those killed.

St. Petersburg, like Moscow, is home to a large diaspora of Central Asian migrants who flee poverty and unemployment in their home countries for jobs in Russian Federation.

"They won't succeed in breaking up our country".

Ryan, a long-time Washington correspondent, has been in the news lately as a target of White House press secretary Sean Spicer's ire with the press.

"I get that at some point they have invested angle and narrative this, and again I'm not going to go into every turn and twist about this, but I think that as I noted yesterday, the more we find out about this, the more we learn that there was clearly something there", he said.

The bombing drew widespread condemnation.

Most of the terrorist attacks in Russian Federation have been connected to the insurgency in Chechnya and other Caucasus republics in the southern part of the country.

There was no immediate claim of responsibility for the blast.

A Moscow-to-St. Petersburg train was bombed on November 27, 2009, in an attack that left 26 dead and 100 injured.

Russian airports also have been targeted.
