Terrorists from Russia"s volatile North...
The explosions, the first in the Moscow metro since February 2004, killed at least 36 people.
Russia"s top investigator Vladimir Markin said police may be able to identify the two female suicide bombers who carried out the attacks. He added that the women"s faces had not suffered in the blasts.
The first attack took place at 7:52 a.m. (03:52 GMT) at the Lubyanka station, located a short distance from the headquarters of the Federal Security Service (FSB), and killed at least 23 people, with another 18 injured.
The second blast detonated some 40 minutes later at the nearby Park Kultury station, within walking distance of the Kremlin. At least 12 people lost their lives and 15 were injured.
Markin earlier told journalists that the second attack had been carried out by a "dark-haired woman" and that "fragments of her body" found at the scene suggested she had had the equivalent of 1.5 kg of TNT strapped to her waist.
