Voice of America - Senior Russian officials say terrorists from the troubled Northern Caucasus could be behind two deadly explosions that ripped through Moscow's subway during morning rush hour on Monday. Female suicide bombers are suspected of carrying out the bomb attacks that killed at least 38 people and injured dozens more.
The blasts occurred during the morning rush hour in central Moscow. The first was at the Lubyanka metro station near the headquarters of the Russian State Security Service, known as the FSB, the successor to the Soviet KGB. The second came 40 minutes later at the Park Kultury station near the city's well-known Gorky Amusement Park.
In a televised Kremlin meeting, FSB Director Alexander Bortnikov said preliminary information indicates the first device contained the equivalent of four kilograms of TNT, the second up to two kilograms. Bortnikov also shared a possible motive. Read more.
The security official says the FSB's preliminary version of the attack points to involvement of terrorist groups from the Northern Caucasus. He says his agency will consider this the working version, because body parts of two female suicide bombers found on the scene link them to the Northern Caucasus.
