Russian authorities told how 'Nevsky express' was blown up

The representatives of special services of Russia informed "Interfax" news agency that a combined charge, which included plastic explosives, was used in the explosive device which went off under the train.

The bomb was equipped with a mechanical decelerator of explosion on the basis of a regular detonator of manual hand grenade UZRGM.

The second explosive device, planted near the scene of the first explosion, did not work at full capacity because of the "umbrella" - the generator of a radio noise turned on by special services in the area of sabotage.

As previously reported, the explosion occurred when the scene was inspected by the ringleader of "Investigation Committee" Alexander Bastrykin. According to one of the versions, the bomb was dampened, so the explosion was not as powerful as the first one and Bastrykin survived.

The first explosion occurred on November 27 at 21:48 at the 284-th km of the Octyabrskaya railway on a stage of Aleshkino-Uglovka. The power of explosion, according to the FSB, was equivalent to 7 kg of TNT, forming a crater diameter of 1 meter to 1.5 meters and depth of 70 cm, two cars were overturned as a result.
