A homemade chemical bomb planted on the tracks in an apparent act of terrorism derailed a high-speed train in Russia carrying hundreds of people Saturday, killing at least 26 and injuring scores more.
The head of the Russian Federal Security Service told the country's news agency Interfax that traces of explosives were found at the train crash site, including chemical residue from a homemade bomb.
Alexander Borotnikov was quoted by the Interfax and RIA Novosti news as saying that an improvised explosive device equivalent to 15 pounds of TNT had detonated when the express train traveling from Moscow to St. Petersburg passed over it Friday night about 9:30 p.m.
No group has been suggested as the perpetrator. Also, bodies continue to be found in the rubble and so we should expect the number of dead and injured to go up.
