Another senseless and outrageous terrorist attack has gripped Moscow today, this time striking the Metro stations of Lubyanka and Park Kultury, as apparently two separate female suicide bombers (raising memories of the black widows) blew up two train cars, claiming the lives of more than 40 innocent people during the morning rush hour.  The potential consequences are unlikely to be positive:  a re-invigorated military campaign in the North Caucasus, wider mandate for authorities to restrict liberties, and a deepening sense of public insecurity … of course it is much to early to speculate.  After the cut are some links and excerpts which piece together the attacks.
