The heads of Russia"s main religious faiths...
The Council of Muftis said "extremism and terrorism have no basis in the Holy Quran."
It said "a terrorist cannot be a Muslim while a Muslim cannot be a terrorist."
Russia"s chief rabbi, Berl Lazar, said he was sure the masterminds of the terrorist attack would get the punishment they deserved.
Patriarch Kirill of Moscow and All Russia, who heads the Russian Orthodox Church, called for solidarity in the face of the tragedy and condemned not only the terrorists but people who have tried to cash in on human grief.
"I"ve just been told that taxi drivers have raised their prices several times just because people are unable to use the metro," he said, warning that "this money will do you no good."
The first attack took place at 7:52 a.m. (03:52 GMT) at the Lubyanka station, located a short distance from the FSB headquarters. The second bomb detonated some 40 minutes later at the nearby Park Kultury station, within walking distance of the Kremlin.
