RIO DE JANEIRO (AP) The Latest on the Olympics in Rio de Janeiro (all times local):
Ryan Lochte says armed robbers posing as policemen put a gun to his head and took his money in Rio de Janeiro.
Lochte described the late-night encounter to NBC's ''Today'' show.
The U.S. swimmer, who won gold in the 4x200 relay at the Rio Games, says armed men came out with a badge and pulled a taxi carrying him and three other American swimmers over.
Lochte says they were told to get down on the ground, but he didn't and they put a gun to his forehead. He says the robbers took money and his wallet, but left his cell phone.
MEDAL ALERT: Max Whitlock of Great Britain won the gold medal in men's floor exercise Sunday.
Whitlock posted a score of 15.633, the first-ever Olympic gold medal for the British in men's gymnastics. Brazil's Diego Hypolito earned silver while teammate Arthur Mariano earned bronze.
Reigning world floor exercise champion Kenzo Shirai of Japan was fourth and two-time Olympic all-around champion Kohei Uchimura was fifth.
American Jake Dalton finished sixth and teammate Sam Mikulak - who posted the highest score during qualifying - was eighth.
Sebastien Dockier scored two goals to help Belgium defeat India 3-1 in the men's field hockey quarterfinals.
India's Akashdeep Singh opened the scoring late in the first period, and the 1-0 lead held up until halftime.
Dockier evened the score early in the third period, then scored again right before the end of the quarter to give Belgium the lead for good. Belgium fired seven shots in the third period after getting just five off in the first half.
Tom Boon's goal four minutes into the fourth period added insurance for Belgium.
The Belgians' only medal in men's field hockey was a bronze in 1920. They didn't qualify for the Games at all from 1980-2004, then finished ninth in 2008 and fifth in 2012.
India was trying to capture its first medal since 1980.
A top IOC official acknowledges parts of the Rio de Janeiro Olympics still do ''not have the look'' that characterizes the games.
Olympic Games executive director Christophe Dubi says ''it's a very unfortunate situation where the look could not be delivered on time.''
Organizing committee officials acknowledged just days before the games opened that only 15 percent of the signage had been installed at Olympic venues. Signs give the Olympics unique branding and help fans get around.
Signage was absent along part of Sunday's women's marathon route, relying on famous backdrops like Sugar Loaf Mountain to remind television viewers that the race was being run in Rio de Janeiro.
Rio organizers have made deep budget cuts hitting all food service, transportation, and volunteers. The cuts were supposed to affect only ''behind-the-scenes'' aspects, but have crept into other areas.
Rio spokesman Mario Andrada says ''we understand that the look of the games needs to be improved in some venues,'' including the Olympic stadium where track and field is held.
The U.S. Olympic Committee says Ryan Lochte and three other American swimmers were robbed by armed men who stopped their taxi in Rio.
USOC spokesman Patrick Sandusky says Lochte and the others left the French Olympic team's hospitality house early Sunday in a taxi headed for the athletes village.
He says ''the taxi was stopped by individuals posing as armed police officers who demanded the athletes' money and other personal belongings.''
Sandusky says the four swimmers are ''safe and cooperating with authorities.''
MEDAL ALERT: Italy's Niccolo Campriani has become the first shooter to win two gold medals at the Rio de Janeiro Games, passing Russia's Sergey Kamensky on his final shot to repeat as Olympic champion in men's 3-position rifle.
Campriani led after the kneeling and prone series, but Kamensky overtook him in the standing portion before eliminations started.
Campriani trailed by 0.6 points heading into his final shot and shook his head with a smile after hitting 9.2. But Kamensky could only muster 8.3 on his final shot, sending a roar across the crowd and Campriani to the top step of the podium for the second time after winning air rifle last Monday.
France's Alexis Raynaud captured bronze his first Olympics.
American Matt Emmons, who earned bronze at the 2012 London Games, did not qualify for the final. He finished 19th after struggling in the standing portion of qualifying.
Ekaterina Makarova and Elena Vesnina have won the Olympic tennis gold medal in women's doubles.
The seventh-seeded Russians beat fifth-seeded Timea Bacsinszky and Martina Hingis of Switzerland 6-4, 6-4 in the final Sunday.
Bacsinszky and Hingis take silver, and Lucie Safarova and Barbora Strycova of Czech Republic had already clinched bronze.
Makarova and Vesnina have won two Grand Slam women's doubles titles together. It's the first Olympic medal for both.
Hingis wins her first medal at age 35, two decades after her last Olympics.
MEDAL ALERT: Russia's Ekaterina Makarova and Elena Vesnina have won the gold medal in women's doubles, beating Switzerland's Timea Bacsinszky and Martina Hingis 6-4, 6-4 in the final. Bacsinszky and Hingis take silver and Lucie Safarova and Barbora Strycova of Czech Republic had already clinched bronze.
Lucie Hradecka and Radek Stepanek have won the bronze medal in Olympic tennis mixed doubles.
The Czechs beat fourth-seeded Sania Mirza and Rohan Bopanna of India 6-1, 7-5 on Sunday.
On Friday, Hradecka was one point from clinching a medal in women's doubles when partner Andrea Hlavackova was struck in the face by a volley, and they went on to lose that semifinal and the bronze medal match.
The mixed doubles bronze is the second Olympic medal for Hradecka, who won silver with Hlavackova in 2012. It's the first for the 37-year-old Stepanek, a two-time major champion in men's doubles.
Czech Republic won three bronzes in Olympic tennis this year, with Petra Kvitova in women's singles and Lucie Safarova and Barbora Strycova in women's doubles also making the podium.
Russia leads after the duet free preliminary in synchronized swimming, where athletes are competing in water that is blue again.
Natalia Ishchenko and Svetlana Romashina totaled 98.066 points on the first day of competition Sunday.
Close behind in second was China's Huang Xuechen and Sun Wenyan at 96.066.
Japan's Yukiko Inui and Risako Mitsui were third at 94.400.
The swimmers are competing in the pool that was used for water polo before that sport resumed its competition at the Olympic Aquatic Stadium as previously planned. The water appears slightly cloudy, but the swimmers are visible underwater, which is vital since they need to be able to see each other as do the judges.
Olympic officials worked through the night draining green-tinged water out of the water polo pool at Maria Lenk Aquatics Center, and pumping in nearly 1 million gallons of clean water for synchronized swimming.
Only two of the Estonian triplets running in the women's Olympic marathon completed the Rio de Janeiro race.
Lily Luik was the fastest of the 30-year-old sisters, clocking 2 hours, 48 minutes, 29 seconds to finish in 97th place Sunday. Luik says the race was hard on a hot and sunny morning and that ''everybody suffered.''
Leila Luik crossed the finish line in 114th in 2 hours, 54 minutes, 38 seconds.
But Liina Luik didn't finish, withdrawing before the 35-kilomter mark.
American fighter Shakur Stevenson has won his first fight in the Olympic boxing tournament.
He remains the prime candidate to win the first men's gold medal in 12 years from USA Boxing.
Stevenson defeated Brazilian fighter Robenilson de Jesus by unanimous decision 30-27, 29-28, 29-28. Stevenson was sharp in the bantamweight bout and busted de Jesus open above the right eye in the second round.
Stevenson attacked him with a series of body shots that forced de Jesus to grab and hold him through the rest of the round.
Stevenson delivered a flurry of uppercuts in the third that left de Jesus shaken against the ropes.
The Newark, New Jersey, native was soundly booed from the moment he was introduced through the final decision. He says he's never been booed like that before.
Andre Ward won the last American boxing gold medal in 2004 in the Athens Games.
Olympic organizers say security forces have detonated what they called a suspicious package outside the Rio Olympics sailing venue at Marina da Gloria.
No further details were immediately available early Sunday afternoon.
A loud bang could be heard from the marina.
The avenue outside the marina was part of the course for the women's marathon earlier Sunday.
Roman Vlasov is one win away from his second-straight Olympic title in Greco-Roman wrestling.
Vlasov advanced to the finals of the 75-kilogram division with a 6-3 win over Croatia's Bozo Starcevic Sunday. Vlasov will face Denmark's Mark Madsen, who is guaranteed of becoming his nation's first Olympic medalist in wrestling since 1948.
Cuba's Ismael Borrero Molina will face Shinobu Ota of Japan in the 59-kilogram class in hopes of extending Cuba's streak of at least one gold medal to at least seven Olympics.
Americans Jesse Thielke and Andy Bisek, both of whom won their first match and lost their second, have been eliminated. Bisek was thought to be the U.S. best hope for a medal in Greco-Roman, a discipline that has long lagged behind freestyle in popularity in the States.
Jelagat Sumgong needed to evade a protester Sunday on her way to becoming the first Kenyan to win the women's Olympics marathon, delivering her country's first gold of the Rio de Janeiro Games.
Sumgong completed the course in 2 hours, 24 minutes, 4 seconds. Kenyan-born Eunice Kirwa, who now runs for Bahrain, was nine seconds behind and world champion Mare Dibaba of Ethiopia took bronze.
Sumgong's gold may have been saved by the swift intervention of security forces with a kilometer to go as she approached the Sambodromo parade area marking the end of the race.
When a man leapt over railings on the right of the road waving a sign, two police motor bikes immediately cut him off.
The protester then jumped over fencing on the left of the road and Sumgong continued unhindered. It was not immediately known if he was arrested. A man also tried to confront Sumgong during the London Marathon in April.
As then, the outcome was the same: Victory for the 31-year-old Sumgong.
Juan Gilardi's penalty stroke with 1:27 remaining in regulation gave Argentina a 2-1 victory over Spain in a men's field hockey quarterfinal on Sunday.
The Argentines advanced to the semifinals for the first time.
Argentina's Gonzalo Peillat opened the scoring with a penalty corner after time had expired in the first period. The Argentines outshot Spain 7-2 in the first half and led 1-0 at the break.
Spain fired a shot off the post on a penalty corner late in the third period. The Spaniards controlled the action for much of the fourth period, and finally got one past goalkeeper Juan Vivaldi when Pau Quemada scored on a penalty corner with four minutes left in regulation.
Seven runners have broken clear of the rest of the field in the women's Olympic marathon at the 30 kilometer mark.
The front-runners are Rose Chelimo and Eunice Jepkirui Kirwa of Bahrain, the Ethiopian duo of Mare Dibaba and Tirfi Tsegaye, Belarusian Volha Mazuronak, Jemima Jelagat Sumgong of Kenya and American Shalane Flanagan.
They're around 40 seconds ahead of the rest of the pack in Rio de Janeiro in hot and sunny conditions.
Tigist Tufa, the 2015 London Marathon champion, pulled up after 18 kilometers.
Darya Klishina, the only Russian athlete in Olympic track and field, has arrived for a hearing to determine whether she can compete.
Klishina's lawyer Paul Greene tells The Associated Press that the Russian long jumper ''plans to say the truth, which is that she's a clean athlete'' when she testifies before the Court of Arbitration for Sport after track's world governing body, the IAAF, withdrew her eligibility for the Olympics.
Greene says the IAAF case against Klishina relies on confidential evidence and ''we haven't had the chance to look at it, to view it, have a science person analyze, nothing, and we believe for that reason we should prevail because I don't think legally that can be upheld.''
If she wins, Klishina will compete in long jump qualifying Tuesday.
The first match of the Olympic wrestling tournament produced one of the biggest upsets the Rio Games will likely see.
Unheralded Japanese wrestler Shinobu Ota stunned seven-time world champion Hamid Soryan of Iran 5-4 in the opening set of Greco-Roman bouts in Arena Carioca 2.
The loss was the second straight international flame-out for Soryan, who has won six world titles in addition to gold at the London Games in 2012.
At last year's world championships in Las Vegas, Soryan was flagged for excessive brutality and ruled ineligible for a medal.
Iran is still expected to factor heavily in the medal chase in Rio. But Soryan's first match wasn't exactly how the wrestling-mad nation wanted to start the week.
Goodbye, green. Hello again, blue. Hope you can stick around awhile.
Synchronized swimmers were greeted by clear blue water in the competition pool Sunday after officials worked through the night to replace murky green water that's become a big embarrassment for Rio Games organizers.
Replacing the water in time for the early-morning training and competition at 11 a.m. local time was a significant challenge - the pool holds nearly 1 million gallons.
But divers were training as expected Sunday morning.
Organizers have insisted there are no health risks posed by the discolored water seen in the pool during and earlier water polo competition and in a different diving pool. Still, visibility underwater is a major issue in synchronized swimming, where competitors spend lots of time underwater and need to be able to see their teammates.
