At least 37 people have been killed after two female suicide bombers blew themselves up on Moscow Metro trains in the morning rush hour, officials say.

Twenty-four died in the first blast at 0756 (0356 GMT) as a train stood at the central Lubyanka station, beneath the offices of the FSB intelligence agency.

About 40 minutes later, a second explosion ripped through a train at Park Kultury, leaving another 13 dead.
