MAKHACHKALA — Two bombs exploded in Dagestan on Sunday, derailing a freight train in an attack that a security source linked to suicide bombings in Moscow and the same region, RIA-Novosti reported.
No one was wounded in the latest attack.
The pre-dawn blasts on a rail line leading from Moscow to Azerbaijan caused nine cars of a train carrying construction materials to derail. Television footage showed pipes spilled from damaged train cars.
"The first data show that this explosion is a continuation of the terrorist attack from fighters of the North Caucasus that started on March 29," a Federal Security Service source told RIA-Novosti, referring to the Moscow metro bombings.
After the first blast derailed eight of the train cars, a second device went off, news agencies reported.
"The device was placed near the railway track, 25 meters from the first one, and was meant to be blown up when police and investigators arrived at the scene," a source in the regional transportation police told Itar-Tass.
