"Putin's paranoia is causing him to surround his residences with more and more radars and air defense systems, taking them from other places. This is creating a hole even around Moscow," says Alexei Alshansky, an analyst with the Farewell to Arms project. Tonight, a drone hit a high-rise building a few kilometers from the Kremlin, on Mosfilmovskaya Street. At least four more drones flying towards Moscow, according to the mayor of the capital, were shot down in the morning and afternoon.
