BBC Sport in Sochi
"Security in Sochi has been prominent as the world's athletes and media arrive for the Games. Threats in recent months have included repeated calls to disrupt the Olympics from the Imarat Kavkaz group in the North Caucasus, suicide bombings in the nearby city of Volgograd, and a recent US warning about the potential for 'toothpaste' bombs on flights.
"Journalists arriving in the region have found hotel rooms and other facilities unfinished amid a last-minute rush by organisers to complete building work, though the Olympic venues themselves have largely met with praise from athletes."
