Revelers(お祭り騒ぎする人)from around the globe are celebrating the start of the New Year with fireworks, bell-ringing, and all-night parties, despite the fear of terrorist attacks in many major cities. In light of the attempted bombing of a US-bound commercial flight on Christmas Day, New Year's celebrations the world over are being policed with increased vigilance(警戒). Despite such fears, an estimated 1.5 million attended Sydney's dramatic waterfront fireworks display, which involved about 11,000 lbs (5,000 kg) of fireworks. Meanwhile, in New York, an estimated 1 million people will brave icy weather to watch the ball drop at midnight in Times Square.
