Authorities have ordered a precautionary evacuation of passengers from the Leningradsky and Yaroslavsky train stations in Moscow after a receiving a bomb threat, a police source said on Sunday.
The source said an anonymous call at around 9 a.m. local time (0600 GMT) claimed that a bomb has been placed at a train station.
A search for a suspected explosive device is ongoing.
Police have also launched checks at Moscow's other train stations in bomb scare.
"The decision on the evacuation from the other train stations has not been taken," a police spokesperson said.
Moscow police have been put on high alert following the deadly terrorist blast at the capital's Domodedovo airport on January 24 which killed 36 people and injured dozens.
Last weekend, police in Moscow evacuated several shopping malls after receiving bomb threats.
