Moscow metro bombings

You've undoubtedly heard the news, especially if you live in a CNN-24/7 country, that two central Moscow subway stations were hit by female suicide bombers.

I don't have much to add at this point, an Izvestia article adds some detail which the NYTimes homepage lacks, namely that the bombers are thought to have connections to the North Caucasus, the explosives were the equivalent of 4 and 2 kg of TNT, that they were made of RDX (also known as T4) and may have had foriegn parts like bolts added. Izvestia article in Russian here.

It would not be surprising to see political effects down the road as well - time will tell.
