Around 40 people have been killed in two explosions on Moscow's metro system.



The explosions happened during the morning rush-hour



The first blast hit a train at central Moscow's Lubyanka metro station during the height of the city's morning rush-hour.


A second explosion is reported to have rocked Park Kultury station, also killing several travellers.


Sky's Russia correspondent, Amanda Walker, said: "The explosion happened at the busiest time. You could not get a busier time.


"It seems to be a very serious situation at the moment."


Emergency ministry spokeswoman Irina Andrianova says 14 people were killed in a train at Lubyanka metro station, just a short distance from the Kremlin.


Eleven more died on the station platform.


Russian media say 12 died in the second explosion.


Russian officials say they are examining whether terrorists were behind the blasts.


Russia's Interfax news agency said the second explosion could have been caused by a suicide bomber.


Chechen rebels have been behind several deadly explosions in the last decade.
But the attacks have receded in recent years.
