In Pictures: Here's How The World Rang In 2020
Cities around the world have put aside worries over international and domestic issues, to ring in the new year and the beginning of the 2020's.
New York has had its turn to ring in 2020, joining countries around the world celebrating the new decade and putting hope ahead of global worries.
Fireworks burst and confetti poured down as throngs of revellers in Times Square counted down the last seconds of 2019 while a luminescent crystal ball descended down a pole.
About 1,360 kilograms of confetti showered the crowd who'd put up with rain and cold as they waited in security pens for the clock to tick over.
Earlier, firework displays around the world contrasted with a background of fires, nuclear weapon concerns and protests.
European capitals had fireworks lighting up the skies over landmarks like Big Ben in London, the Arc de Triomphe in Paris, the Parthenon in Athens and the Kremlin in Moscow.
Londoners saw a glittering display launched from the London Eye and barges on the Thames near Parliament, with the familiar chimes of the Big Ben clock tower ringing in the new year, after extensive restoration work.
To the north, the multi-day Hogmanay New Year's celebrations in Edinburgh began on Monday night with a torchlight parade through the streets of the Scottish capital.
North Korea also marked the new year, but there's concern about its hints of fireworks of a different kind. Kim Jong Un said on Wednesday his country would introduce a "new strategic weapon" in the near future, after the US missed a year-end deadline to restart denuclearisation talks.
Thousands in Hong Kong welcomed 2020 at Victoria Harbour, breaking into pro-democracy chants shortly after the countdown to midnight.Hong Kong authorities cancelled the main midnight fireworks display for the first time in a decade, citing security concerns. Social media posts urged protesters to wear masks at a New Year rally called "Don't forget 2019 - Persist in 2020".
Thousands of Indians ushered in the year by demonstrating against a citizenship law they say will discriminate against Muslims and chip away at India's secular constitution.
