Calls were from all four Moscow airports, five railway stations, 15 shopping malls, several hotels, more than 20 schools and many other venues, the state Tass news agency said. No explosives have been found in the anonymous calls.
Flights to and from Moscow weren’t affected, as security agents at the airports checked for explosives without evacuations.
