Russian Prime Minister Putin has just declared on the NTV television news channel that “according to the preliminary results of the investigation the terrorist act is not linked to the Chechen Republic” (Нынешний террористический акт не имеет отношения, по предварительным данным следствия, к Чеченской республике).
According to Russian sources, the terrorist was, quote, “of a Mediterranean type which would include Arabs”, unquote.

More details soon, hopefully.
