PARIS – In Bangkok, police-flanked partygoers will ring in the new year at the site of a deadly bombing that took place just months ago. In Paris, residents recovering from their city's own deadly attacks will enjoy scaled-back celebrations. And in Belgium's capital, authorities anxious after thwarting what they say was a holiday terror plot have canceled festivities altogether.
The Federal Prosecutor's Office in Belgium said six people were brought in for questioning and seven searches carried out Thursday morning in various Brussels-area locations in connection with a suspected plot to stage extremist attacks over the holidays.
As the final hours of 2015 draw to a close, many are bidding a weary and wary adieu to a year marred by attacks that left nations reeling and nerves rattled. Still, most places are forging ahead with their celebrations as many refuse to let jitters ruin the joy of the holiday.
"We still have this fear but we need to continue to live," said Parisian Myriam Oukik. "We will celebrate."
A look at how people around the world are doing exactly that:
The French are still recovering from the Nov. 13 attacks that left 130 people dead in Paris, and authorities are preparing for a possible worst-case scenario on New Year's Eve. About 60,000 police and troops will be deployed across the country on Thursday.
"The same troops who used to be in Mali, Chad, French Guyana or the Central African Republic are now ensuring the protection of French people," said Defense Minister Jean-Yves Le Drian.
The French are reeling after a year that started with attacks on satirical newspaper Charlie Hebdo Jan. 7 and on a Paris kosher market two days later, violence that killed 17 people plus the three Islamic extremist attackers.
In the ensuing months, attacks were thwarted on a church and a high-speed international train, and another Islamic extremist decapitated his boss at an American-owned chemical plant.
Paris has canceled its usual fireworks display and will instead display a 5-minute video performance at the Arc de Triomphe just before midnight, relayed on screens along the Champs Elysée.
Paris mayor Anne Hidalgo said the show will be aimed at "sending the world the message that Paris is standing, proud of its lifestyle and living together."
In previous years, more than 600,000 French and foreign visitors gathered on the famous avenue for New Year's Eve. This year, it will be closed to vehicles for just one hour instead of the usual three.
"It was a very strange year and we just want 2016 to be different, simply a normal one," said Parisian Francoise Malterre. "It does not need to be an excellent one, but just a normal one."
Security was beefed up in Malaysia's biggest city, Kuala Lumpur, where fireworks were to ring in the new year at a historic square as well as at the Petronas Twin Towers, one of the world's tallest buildings.
Malaysian authorities have detained more than 150 suspects linked to the Islamic State extremist group over the past two years, including some who were allegedly plotting to launch attacks in strategic areas of Kuala Lumpur.
No specific threats timed for New Year's revelries were detected in the capital, Manila, or other major cities, although government forces are always on alert due to the presence of small but violent Muslim militant groups in the country's south.
Concern on New Year's Eve was instead focused on the use of illegal fireworks, which last year injured more than 850 people. Shopping malls and cities organized fireworks displays to discourage people from lighting their own firecrackers. A huge religious sect, the Iglesia ni Cristo, was to attempt to break the world record for the largest fireworks display and the highest number of sparklers to be lit in one place.
An annual procession of the Black Nazarene, a black wooden statue of Jesus Christ, was held a day earlier than usual Thursday to prevent injuries from mounds of trash and unexploded firecrackers that litter Manila's streets after New Year's revelries. A larger procession of the statue will be held Jan. 9.
New Year's Eve is Japan's biggest holiday, and millions crammed into trains to flee the cities for their hometowns to slurp down bowls of noodles, symbolizing longevity, while watching the annual "Red and White" song competition on television. As midnight approached, families bundled up for visits to neighborhood temples, where the ritual ringing of huge bronze bells reverberated through the chill.
Tokyo is on special alert for security issues this year, with posters in subways and other public spaces warning people to keep their eyes open for suspicious packages or activities.
South Koreans marked New Year's Eve with traditional bell ringing ceremonies, fireworks and outdoor music and dance performances. Thousands of people, including North Korean refugees, were expected to gather at a town near the border with rival North Korea to watch one of the ceremonies and wish for peaceful Korean unification.
North Korea was expected to mark the new year with a speech by leader Kim Jong Un, which outside observers pore over for insight into the reclusive country's policy directions.
New Zealand, the first nation with a sizable population to celebrate the New Year, counted down the seconds to midnight with a giant digital clock on Auckland's landmark Sky Tower. Horns blared and crowds cheered as the tower was lit up with fireworks, with colors shifting from green to red to white.
Simultaneous fireworks displays erupted along Sydney's famed harbor, where people crowded onto balconies, into waterside parks and onto boats as they jockeyed for the best view, clinking glasses and whooping with joy as the first pyrotechnics exploded.
More than 1 million people were expected to watch the glittery display, featuring a multicolored firework "waterfall" cascading off the Harbour Bridge and effects in the shapes of butterflies, octopuses and flowers.
Australian officials, struggling to contain the threat from home-grown extremists, encouraged revelers to enjoy the evening and assured them that thousands of extra police were patrolling major cities.
"Don't change your way of life," Melbourne Lord Mayor Robert Doyle urged residents of his city. "Don't let events from around the world challenge the way that we live."
An official New Year's Eve celebration was planned near Beijing's Forbidden City with performances and fireworks, and one of China's most popular TV stations broadcast a gala from the National Stadium, known to most as the iconic Bird's Nest.
For safety reasons, Shanghai closed subways near the scenic waterfront Bund because of a stampede last New Year's Eve that killed 36 people and blemished the image of China's most prosperous metropolis.
Beijing's shopping and bar areas are under a holiday security alert that started before Christmas and has resulted in armed police standing guard at popular commercial areas. Police commonly issue such alerts during holiday periods.
Less than six months after a pipe bomb killed 20 people at the Erawan Shrine in Bangkok, tens of thousands were expected to ring in the new year at the same intersection with live music and a countdown.
Up to 5,000 police were in the area, with explosive ordnance disposal experts sweeping the area ahead of time.
Noisier still will be the celebration along the Chao Phraya River, where tourism officials planned spectacular fireworks over two of the kingdom's most iconic landmarks, the Grand Palace and Wat Arun — the Temple of Dawn.
Indonesia is on high alert after authorities said last week that they had foiled a plot by Islamic militants to attack government officials, foreigners and others. About 150,000 police officers and soldiers have been deployed to safeguard churches, airports and other public places.
National Police spokesman Maj. Gen. Anton Charliyan said security is focused on anticipating attacks in vulnerable regions including the capital, Jakarta, the tourist resort of Bali and restive West Papua, where President Joko Widodo is celebrating the New Year.
More than 9,000 police are deployed in Bali, the site of Indonesia's deadliest terror attack, which killed 202 people in 2002.
Hotels and restaurants in and around New Delhi have been advertising grand party plans with live bands, dancing and plenty of drinks.
With security a concern, police and anti-terrorism squads on Tuesday conducted drills at a crowded shopping mall and food court. Witnesses, however, were unimpressed. Mona Arthur, a Delhi journalist who was in the mall at the time, dubbed the exercise a "mockery of a mock drill."
She and a friend were shopping when two police officers ran past them. Then a security official said two terrorists had entered the mall.
"The whole thing was comical," said Arthur, who was irritated that no information was given to shoppers on where to go or what to do.
UNITED ARAB EMIRATES
In the megacity of Dubai, three separate firework displays are set to wow spectators. The show starts from the Burj Khalifa, the world's tallest building at 828 meters (905 yards). Already, organizers say the tower has been fitted with 400,000 LED lights and 1.6 tons of fireworks will be used in the display.
From there, fireworks also will light up the sky around the sail-shaped Burj Al Arab and later down near the Dubai Marina. Fireworks also will be on display in Abu Dhabi, the capital of the country of seven emirates.
The fireworks will end a year of challenges for the United Arab Emirates, which saw global oil prices drop below $40 a barrel and dozens of its soldiers killed in the ongoing Saudi-led war against Shiite rebels in Yemen. Meanwhile, the Mideast as a whole still reels from the onslaught of the Islamic State group.
Nada Fayez, 46, a mother of four teenagers, planned to celebrate the New Year at home with her family. She said the security situation in Jordan is stable and she would have no concerns if her sons and daughter preferred to go out for celebrations.
Jordan has taken a high-profile role in the U.S.-led military campaign against the Islamic State extremist group, which controls large areas of neighboring Syria and Iraq.
Security has been beefed up in the streets of Amman, as well as in malls and hotels.
Gaza's Islamist Hamas rulers banned New Year celebrations in the Palestinian coastal enclave. Police spokesman Ayman Batniji said hotels and restaurants were allowed to hold parties a day earlier, or a day later.
"Celebrating the new year contradicts the instructions of Islamic religion," Batniji said. "It's a Western custom that we don't accept in Gaza."
The militant Hamas group wrested control of Gaza, home to 1.8 million people, from forces loyal to Palestinian President Mahmoud Abbas of the secular Fatah movement in 2007.
Police in Kenya, which has been repeatedly attacked by al-Shabaab militants based in neighboring Somalia, are urging vigilance as many people prepare to celebrate in hotels and watch midnight fireworks displays. Unauthorized fireworks have been banned as a safety hazard "in view of the elevated threat of terrorism," police said.
"Kenyans should remain vigilant at all times and know that we are facing a real terror threat since the split of al-Shabaab into two groups, one supporting al-Qaida and another Islamic State," Inspector General of Police Joseph Boinnet told The Associated Press. "We are facing a real terror threat because these two groups are struggling to outsmart each other. This therefore is not a time to drop our guard, particularly during this festive season."
In Brussels, 2016 will be rung in without the customary fireworks display and downtown street party. The festivities were canceled by Mayor Yvan Mayeur, who said Wednesday evening it would have been impossible to administer adequate security checks to all of the 100,000 people expected to attend.
Earlier this week, Belgian authorities announced they had arrested two men suspected of planning to stage attacks in Brussels over the holidays. On Thursday, six more people were brought in for questioning.
A total of 10 people have also been detained in Belgium for suspicion of involvement in the attacks that killed 130 people in Paris on Nov. 13.
On Thursday morning, forklifts and trucks removed generators and other equipment from the Place de Brouckere, the broad square in central Brussels where the fireworks show was supposed to happen. Some people said they understood the cancellation, others called it knuckling under to the extremist threat.
"I think it is a good and wise decision," said Koen Vandaele, a Brussels resident. "There could be a lot of confusion if the fireworks started" and there was a fresh attack.
"I think it is backing down to the threat to terrorism," disagreed Ken Kinsella, another Brussels resident. "There is no point in running away from it so I think they should have gone ahead with it."
Computer materials, cellphones and equipment for airsoft, a sport that uses replica firearms to fire non-metallic pellets, were confiscated in the searches, the prosecutor's office said. Previous searches in the case led to the impounding of military-style training uniforms and IS propaganda material, investigators said.
Up to a million revelers were expected at Berlin's annual New Year's Eve party at landmark Brandenburg Gate. Authorities searched nearby Tiergarten park and fenced off the entire area. Big backpacks and bags, fireworks and sharp objects were banned from the party zone around the gate.
Traditionally, Germans welcome the new year with fireworks, jelly doughnuts and lots of champagne and sparkling wine.
Major celebrations marked by fireworks spectaculars are planned in London, Edinburgh and other big cities despite a terror threat judged to be "severe." Scotland Yard plans a major deployment of roughly 3,000 officers in central London, including hundreds of specially trained and equipped firearms officers. Police said "all available staff" will be called on to protect people at the festivities.
Police advised revelers not to come to the fireworks display without a ticket and to be ready to have their belongings searched.
Police have thwarted a number of attacks this year as a tiny but increasing number of British Muslims have endorsed the cause of Islamic State extremists.
Rio de Janeiro's main soiree on Copacabana Beach will have dual themes: the 100th anniversary of samba music and the kickoff to the Olympics, which the city will host in August. More than 2 million people are expected on the beaches Thursday.
Police say more officers will be on hand this year than the 1,600 deployed for last year's bash. Capt. Ivan Blaz, spokesman for Rio's police force, told The Associated Press that they have received no reports of extremist threats.
The partying will happen at a time when Brazil is mired in crisis. The economy has plunged, the opposition is pushing to impeach President Dilma Rousseff and a host of financial and government scandals have soured Brazilians.
Around 1 million people are expected to converge on New York City's Times Square for the annual celebration. The party begins with musical acts, including Luke Bryan, Charlie Puth, Demi Lovato and Carrie Underwood, and ends with fireworks and the descent of a glittering crystal ball from a rooftop flagpole.
This year's festivities will also be attended by nearly 6,000 New York City police officers, including members of a specialized counterterrorism unit.
People usually begin filling the square and adjoining blocks before sundown for the televised spectacle. Everyone arriving will be screened for weapons with a metal-detecting wand.
Officials are urging revelers to leave bags, backpacks and strollers at home as police ready for hundreds of thousands of partiers to flood the Las Vegas Strip. It's not a first-of-its-kind request, but it's getting extra emphasis following deadly attacks in Paris and San Bernardino and, more recently, a driver in Las Vegas who witnesses say intentionally plowed into pedestrians, killing one person.
Nearly 1,000 uniformed officers and an undisclosed number of undercover officers will be posted along the popular 4-mile-long, casino-filled corridor.
Las Vegas Mayor Carolyn Goodman lamented the prospect that fear might keep people from celebrating New Year's Eve, or any event.
"It can't be. We cannot let that rule," she said.
