Russia insider commits: Moscow attack “staged by the Kremlin”. Russia expert Gerhard Mangott supports Anders Åslund's assumptions.
According to Mangott, Putin is under pressure: “They have now to cover up their failures with retaliatory actions” The death toll has now risen to 139 and there are also more than 180 injured. An offshoot of the Islamic State group from Khorasan Province claimed responsibility for the attack, and the claim is generally considered credible.
