Revellers around the world have been celebrating the end of 2011 and seeing in 2012.
A multi-million dollar firework display heralded in the new year in Sydney, while the world's tallest building, the Burj Khalifa, was illuminated in Dubai.
Celebrations were held across Europe, with some 250,000 gathering to watch fireworks over the River Thames.
In Times Square in New York, crowds watched Mayor Michael Bloomberg and Lady Gaga count down to midnight.
The traditional ball, lit this year with 30,000 lights, descended a high pole as the New Year began and Frank Sinatra's New York, New York was played.
In Los Angeles, the last major population centre to see in the new year, hundreds of extra firefighters were deployed across the city to combat a wave of arson attacks that has seen more than 30 fires lit since Thursday night."
