Boston Bombers are from Chechnya

From the Guardian:

If it is established that the bombs in Boston were planted by Chechens, it would mark an unprecedented development: the first time militants from the former Soviet republic have carried out a deadly attack outside Russia.

In their long, violent struggle against the Kremlin, Chechen radicals have hit soft targets before. In 2010 two female suicide bombers from Dagestan blew up the Moscow metro, killing at least 40 people and injuring 100. A year later another suicide bomber struck Moscow's Domodedovo airport; he killed 37 and wounded 180. There have been murderous attacks including the one on a school in Beslan in 2004, where 334 hostages died, most of them children.

But the bombing of the Boston Marathon, which police suspect was perpetrated by two Chechen brothers, Dzokhar and Tamerlan Tsarnaev, are something altogether new. It is so far unclear how significant is the trail that appears to lead from the mountains of the North Caucasus – the scene of a simmering ongoing insurgency – to the boulevards and suburban houses of North America.
