'Suicide blast' hits Moscow station
The blast happened at the end of the evening rush-hour
At least eight people have been killed in an explosion in a car outside an underground railway station in Moscow.
At least 10 others were hurt in what may have been two blasts outside the Rizhskaya station in the north of the city, reports say.
Russian security officials are blaming the attack on a female suicide bomber.
Television pictures from the scene show a car on fire and wounded people on the ground as ambulances and rescue services rush to the scene.
More than a dozen bodies could be seen scattered on the pavement and grass surrounded by pools of blood.
"There are children among the wounded," a police source was quoted as saying.
The station's windows and those in nearby shopping centre were blown out by the force of the blast, which happened soon after 2000 (1600 GMT).
The underground station is on one of the busiest routes to the north of the city, says the BBC's Damian Grammaticus in Moscow.
A source at the interior ministry was quoted by Interfax news agency as saying: "With a great deal of probability, we can state that what happened was a deliberate explosion caused by a female suicide bomber."
Police have been on high alert after a bomb exploded at a south Moscow bus stop last week.
On the same day, 89 people died when two passenger planes exploded mid-flight.
It is thought they were brought down by suicide bombers with links to Chechnya.
