BBC: At least 35 people have been killed after two female suicide bombers blew themselves up on Moscow Metro trains in the morning rush hour, officials say. Twenty-three 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 12 dead. No-one has said they carried out the worst attack in the capital since 2004. But the BBC’s Richard Galpin in the Russian capital says past suicide bombings there have been blamed on Islamist rebels fighting for independence in the troubled North Caucasus region of Chechnya. In February, Chechen rebel president Doku Umarov warned that “the zone of military operations will be extended to the territory of Russia… the war is coming to their cities”. MORE
NEW YORK TIMES: The two explosions spread panic throughout the capital as people searched for missing relatives and friends, and the authorities 
tried to determine whether more attacks were planned. The subway system, known as the Metro, is one of the world’s most extensive and well-managed, and it serves as a vital artery for Moscow’s commuters, carrying as many as 10 million people a day. “The terrorist acts were carried out by two female terrorist bombers,” said Moscow’s mayor, Yuri M. Luzhkov. “They happened at a time when there would be the maximum number of victims.” Photos taken after the attacks showed scenes of devastation, with bodies strewn across subway cars and station platforms.

THE TELEGRAPH: Islamist rebels seeking to establish an Islamic caliphate on Russia’s southern tip have largely confined their attacks to the North Caucasus area they want to control in recent years. But a bombing of a passenger train between Moscow and St. Petersburg last November that left dozens dead suggested they may be preparing to widen their campaign to Russia’s big cities. Russian security forces claim to have killed a number of high profile militants in recent months including one of the movement’s principal ideologues and strategists. Russian politicians said at the time that the rebels were likely to strike back to show they are still a force with which to be reckoned. MORE
