MOSCOW. Jan 29 (Interfax) - Administrative buildings in Moscow received bomb threats on Wednesday, an informed source told Interfax.
"Bomb threats have been sent to a wide range of Moscow hospitals, about ten buildings are being inspected," the source said.
Emergency services in Moscow are also verifying information concerning bombs allegedly planted in the Moscow region's duma building.
The anonymous threats are being made on Wednesday amid a statement by the Federal Security Service (FSB) on having blocked the foreign mail service from which they are being sent. The service is Swiss Protonmail.com, which the unidentified criminals began using after similar Dutch service Startmail.com was blocked, the FSB said.
