More than 3,000 people have been evacuated from train stations in Moscow amid bomb threat fears. Police officers are now checking out three stations – Kazansky, Leningradsky and Yaroslavsky – with sniffer dogs to search for any explosive devices. All three stations sit on the same square in Moscow and there are fears that coordinated attacks could have been planned.

According to a source, phone calls were received warning that there were bombs at both the Kazansky and Leningradsky railway stations, leading to swift evacuations of travellers from both sites. A further 750 people were asked to leave the third station while specialist units were called in.

No bombs found

However, following an extensive search with explosive-sniffing dogs, no devices have been found, according to news agency reports. There are no further details about the exact nature of the threat, or who made it. However, it was clearly enough to make the Russian authorities take it seriously and move quickly to protect civilians.

This latest scare follows reports that the Tu-154 Russian military plane, which crashed into the Black Sea just a couple of minutes after take off could have been brought down by terrorists. All 92 people on board are understood to have died, while the search for bodies continues.

The craft had disappeared from radar just two minutes after taking off from Sochi. It was set to go to Latakia in Syria where 64 members of the famous Alexandrov military music ensemble were due to perform at a Russian troop base. So far, debris and 11 bodies have been found, and there are no reports of any survivors. More than 100 divers are continuing to search for bodies amid the wreckage at the crash site. While Russian authorities first downplayed any suggestion of terrorism, they now say that air crash investigators have not ruled anything out.
