A 'laboratory of death' has been destroyed in a special operation in Dagestan in Russia's North Caucasus.
Around a dozen powerful home-made bombs were discovered in an underground compound hidden in a forest. A number of cellphones, which could have been used to trigger explosions, were also seized. The operation came about after a terror suspect was arrested in the same area. "The timely destruction of a 'death lab' and neutralization of 13 IEDs [improvised explosive devices] with a total power equivalent to that of 90kilograms of TNThas made it possible to avert a series of terrorist acts in the Republic of Dagestan and to avoid numerous human fatalities," said a spokesman for the the National Anti-terror Center.Federal Security Service (FSB) experts said similar bombs had repeatedly been used in rail attacks."After all necessary investigations the laboratory was destroyed by an explosion," said an FSB spokesman.
