A second blast at the site of the terrorist...
Three cars of the Nevsky Express high-speed train from Moscow to St. Petersburg derailed Friday evening after an explosive device equivalent to 7 kg (15 lbs) of TNT detonated on the railroad tracks. A second, weaker bomb exploded on Saturday at 2:00 p.m. (11:00 GMT) at the site of the attack.
There were no injuries or casualties reported from the second blast.
According to the latest information, 26 people were killed and more than 90 injured when the train derailed. A criminal case into the Nevsky Express bombing was launched on charges of terrorism.
Forensic examination established that the second explosive device had a remote detonator, and was activated using a cell phone.
"It gives us grounds to believe that the second explosion near the site of the [first terrorist attack] could have been targeted directly at the investigative group," the committee said in a statement, adding similar tactics are often used by militants in the North Caucasus.
