    An explosion at a Russian train station Sunday afternoon killed at least 16 people, including a police officer, and injured 34 more. Authorities say a female suicide bomber detonated her explosives before going through a metal detector in Volgograd's central station. The bomber's remains is set to undergo DNA testing, and no group has claimed responsibility. In October, six people were killed when a female suicide bomber blew up a bus in the city, which is located about 600 miles from Sochi, host of the upcoming Winter Olympics.
