A suicide bomber set off a blast in the entrance hall of a Russian train station on Sunday, investigators said, killing at least 16 people in the second deadly attack within three days as the country prepares to host the Winter Olympics.

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 north of the violence-plagued North Caucasus region on Russia's southern fringe.
