MOSCOW (AP) -- Russia's Federal Security Service said Tuesday that it had concluded that the explosion on Moscow's subway earlier this month that killed 41 people was the work of a suicide bomber, Russian news agencies reported.
The bomb that exploded on Feb. 6 was equivalent in force to 9-11 pounds of TNT and was made of ammonia saltpeter and aluminum powder, the ITAR-Tass and Interfax news agencies reported, citing the security service's press office.
The makeup of the bomb was identical to one used on a commuter train in the southern Russian city of Yessentuki in December, the security service said. Security service officials had already said there was a connection between the two blasts.
Forty of the 41 Moscow bombing victims have been identified, the news agencies said. More than 100 people were wounded in the blast, which President Vladimir Putin and other officials blamed on Chechen rebels.
