At least 37 people were killed and 33 wounded on Monday when suicide bombers detonated explosives on two packed Moscow metro trains during the morning rush hour, the worst attack in the Russian capital in six years, officials said.
No group immediately claimed responsibility for the blasts but suspicion was likely to fall on groups from the North Caucasus, where the Kremlin is fighting a growing Islamist insurgency.
The first blast just before 8 a.m. tore through the second carriage of a train as it stood at the Lubyanka metro station, close to FSB headquarters. It killed at least 23 people.
Another blast about 40 minutes later wrecked the second carriage of a train waiting at the Park Kultury metro station, killing 14 more people.
"Two female terrorist suicide bombers carried out these bombings," Moscow Mayor Yury Luzhkov told reporters at Park Kultury metro station.
Surveillance camera footage posted on the Internet showed motionless bodies lying in Lubyanka station lobby and emergency workers treating victims.
The Moscow metro system is one of the world's busiest, carrying about 7 million passengers on an average workday, and is a key element in running the sprawling and traffic-choked city.
The blasts practically paralyzed movement in the city center as emergency vehicles sped to the stations. Helicopters hovered over the Park Kultury station area, which is near the famous Gorky Park.
Service on the Red Line, on which both stations are located, has been suspended from Park Kultury to Komsomolskaya.
Passengers, many of them in tears, streamed out of the station, one man exclaiming over and over "This is how we live!"
At least a dozen ambulances were on the scene.
The ruble fell to 34.25 from 34.13 against the Central Bank's dollar-euro basket. Russian equity markets opened down 0.15 percent.
Prosecutors said they had opened an investigation. Prime Minister Vladimir Putin was being updated regularly on developments, a spokesman said.
The current death toll makes it the worst attack on Moscow since February 2004, when a suicide bombing killed at least 39 people and wounded more than 100 on a metro train.
Chechen separatists were blamed for that attack.
