Up to 3,000 passengers and staff have been evacuated from three rail terminals in Moscow on Monday following bomb threats, according to Russia’s state-run news agency Sputnik.

“Phone calls warning of bombs at the Kazansky and Leningradsky railway stations prompted evacuations of a thousand of people from each site. Further 750 people were evacuated from the Yaroslavsky station. We are waiting for explosive-sniffing dogs,” Sputnik, the English language version of RIA Novosti, said Monday citing a source in the emergency services.
