The Moscow Metro, which spans almost the entire Russian capital, is the world's second most heavily used metro system after Tokyo's twin subway.
 

The Lubyanka Station is on the Sokolnicheskaya Line of the Moscow Metro, located under Lubyanka Square.
 

The square houses the former headquarters of the KGB and the Lubyanka prison. It now houses the Border Guard Service of Russia, which is the nation's federal security service which succeeded the KGB.
 

It is located a third of a mile from the Kremlin.
 

Spokeswoman for the Russian emergencies ministry Irina Andrianova told ITAR-TASS 15 people were killed in the train at Lubyanka and 11 on the platform.
 

Sky News reported the explosion struck the second car of the train.
 

The Russian capital over the last decade has been hit by a string of deadly explosions claimed by militants from its turbulent southern region of Chechnya but this has become less frequent in the last years.
