Half of the United States thinks it's at least somewhat likely there will be a terrorist attack at the Winter Olympics in Sochi, Russia, next month, according to a new poll.
Recent threats to some European countries' Olympics offices have largely been dismissed as hoaxes, but there continue to be concerns about an attack marring the games.
Terrorist threats have become a part of almost every Olympic Games in recent years, with attacks on Munich in 1972 and Atlanta in 1996 being among the most well-known.
