Investigators in southern Russia say two deadly bombings in the city of Volgograd appear to follow the pattern of attacks by Islamist separatists from the nearby North Caucasus region. It's a dire concern for the Russian authorities, who worry that this could be the lead-up to attacks during the Olympic Games in Sochi in February. Security analysts say the bombings could even be a diversionary tactic to distract the security forces before an even bigger attack. It also raises concerns about security for New Year's crowds in major Russian cities.
