World welcomes 2013 with wave of fireworks

Spectacular fireworks exploded over Sydney in a blaze of light and colour on Tuesday to ring in the New Year, as the city kicked off a wave of global celebrations from Dubai to London to welcome 2013. Australia's famous harbour city brought in the New Year on a balmy summer night with a US$6.9 million display curated by pop icon Kylie Minogue, who pressed the button to start the pyrotechnics.
