Update X 1: BBC reports 40 dead now in a "highly coordinated attack"-(BBC World Service TV)
At least 25 people are reported to have been killed in an explosion on the Metro system in central Moscow, with a second blast coming shortly afterwards.
The first blast happened at the city's central Lubyanka station, reports quoting security sources said.
A second explosion happened at the Park Kultury station, Russian news agency Tass reported.
Ten people were injured in the first blast, Tass said, quoting the emergencies ministry.
There may have been multiple targets. What is very concerning is that this subway blast was near the Kremlin and Moscow has the 2nd largest subway system after Tokyo in the world, 2nd largest usage that is. Millions of people use the system.
