Millions of people around the world shrugged off terror jitters to ring in 2017 in style, as Sydney kicked off the party with a spectacular fireworks display that lit up its iconic harbour.
Revelers crammed into major cities to celebrate New Year with security tightened amid fears large crowds of people could present a target for extremists.
Getting the festivities started was Sydney, where around 1.5 million people thronged Australia's biggest city to watch midnight fireworks erupting from the Harbor Bridge.
Crowds in Hong Kong also flocked to the waterfront to watch fireworks explode over Victoria Harbor while in Japan thousands packed the streets of Tokyo to release balloons into the air.
Celebrations swung into Europe with the night sky over Moscow's Red Square literally painted red by the fireworks.
And nearly 500,000 people were expected on Paris's famous Champs-Elysees, where the Arc de Triomphe was lit up with a colorful countdown to 2017 and the word "welcome" in dozens of languages.
The raucous celebrations drew to an end a year of political shocks, from Britain's vote to leave the European Union to the election of maverick leaders in the United States and Philippines.
It has also been a year of celebrity deaths from David Bowie to Prince and Mohammed Ali.
2016 was also a year of bloodshed and misery that has seen the war in Syria, Europe's migrant crisis and numerous terror attacks dominate the headlines.
