MOSCOW, July 14. /TASS/. Five establishments in Moscow, including the Helmholtz Research Institute of Eye Diseases, have received bomb threats, an emergency source told TASS on Tuesday.

"Anonymous bomb threats have been reported in five buildings, including the children’s department of the Helmholtz Research Institute of Eye Diseases," he said, adding that probes were underway but none of the buildings had been evacuated.

A wave of bomb threats hit Russia in November 2019. Since then, schools, shopping malls and courts have been repeatedly receiving bomb threats. All bomb threats have so far proved to be false alarms. Russia’s Federal Security Service (FSB) said that access to five foreign websites used for sending messages about bombs had been blocked.
