Explosive device on subway train in St. Petersburg kills at least 10 people

A large explosion tore apart a train as it traveled between two central St. Petersburg metro stations Monday, killing at least 10 people and injuring dozens, Russian officials said.

Russia’s National Anti-Terrorism Committee said the explosion was caused by “an unidentified explosive device,” but it gave no other details. Russia’s Investigative Committee also opened a criminal investigation.

The entire St. Petersburg subway system was shut down as a precaution, and security was boosted around the city, where Russian President Vladi­mir Putin was holding talks with Belarusan leader Alexander Lukashenko.

“I have already talked to the chiefs of special services, the [Federal Security Service] director,” Putin said in televised remarks at the meeting with Lukashenko, a key Russian ally. “The law enforcement agencies and special services are working, and they will do everything to find out the causes of the incident and make a full assessment of what has happened.”
