The Russian tabloid LifeNews, which has uncannily good access that we won’t ask questions about, has published photos of the severed heads of the two female suicide bombers. The Lubyanka bomber (the second set of pictures) looks extremely young, and her age is estimated at 25. Clickers beware: it is extremely graphic.
(NB: LifeNews is known for having extremely good connections to the siloviki, which is how they often get materials like this. And I mean, often. In this case, they said they talked to the workers at the morgue where the terrorists’ remains were taken. But security has been tight at the hospitals and morgues, so, again, the connections certainly played a role.)
