At least 16 people have been killed after a suicide bomber detonated explosives in the entrance hall of a Russian train station, Reuters reported, citing investigators.
Authorities said the attacker detonated a shrapnel-filled bomb in front of a metal detector just inside the main entrance of the station in Volgograd, a busy hub in southern Russia.
It marks the second deadly attack within three days as Russia prepares to host the Winter Olympics in Sochi.
