Mykyta Nesterenko of Ukraine kicked it off in front of a quarter-filled Olympic stadium with the first discus throw in men's qualifying.
The women's heptathlon is underway, too, with the 100-meter hurdles. Brianne Theisen-Eaton of Canada and Jessica Ennis-Hill of Britain are expected to vie for the title.
Later this morning is qualifying for the men's 800.
There will be three medal events – in the women's shot put, women's 10K and men's 20K race walk.
The evening's highlight is qualifying heats for the women's 100.
Usain Bolt is still waiting. He won't take to the track until noon Saturday for the first round of the men's 100.
Brazil's government has declared a day of official mourning for a Rio Olympics police officer who died after being shot in the head making a wrong turn into a Rio slum.
Interim President Michel Temer's decree honoring Helio Vieira was published Friday.
Vieira, one of 85,000 security forces providing security for the games, had been sent to Rio from the northern state of Roraima.
The truck he was driving Wednesday was sprayed with bullets entering the Vila do Joaa slum next to a highway leading to Rio's international airport. Two other national security force members were injured in the same attack but have been released from the hospital.
Justice Minister Alexandre de Moraes expressed his condolences on Facebook, calling Vieira ''our true hero.''
In Kenya, the High Court has released on bail the track and field Olympic team manager who is being investigated on allegations that he helped cover up doping for cash.
Michael Rotich was sent home from the Rio de Janeiro Olympics by Kenyan authorities after the British newspaper The Sunday Times reported allegations that he agreed to take a 10,000-pound ($13,000) bribe in exchange for helping athletes beat doping tests.
High Court Judge Luka Kimaru on Friday overturned an earlier decision by a Magistrates Court that granted police authority to hold Rotich for 28 days while investigating the allegations. Kimaru says the decision to hold the official wasn't based in law.
Kimaru granted Rotich a $2,000 cash bail and a surety of about $10,000.
It's Day 7 at the Rio Games and athletes are vying for 25 gold medals in 13 different sports.
American superstar Michael Phelps is looking to claim his 23rd Olympic gold with a standout performance in the 100 meter butterfly, while teammate Katie Ledecky is aiming to dominate the women's 800 meter freestyle final.
Track and field is starting up and two women will each be seeking a third consecutive gold: Tirunesh Dibaba of Ethiopia in the 10,000 meters and New Zealander Valerie Adams in the shot put.
On the tennis court, Rafael Nadal of Spain will team up with Marc Lopez to face Romania in a gold medal doubles match, while in boxing, American Nico Hernandez will be fighting for gold against Uzbekistan's Hasanboy Dusmatov.
Medals will also be awarded in archery, track cycling, equestrian, fencing, judo, rowing, shooting, trampoline gymnastics and weightlifting.
A play-by-play announcer for Canada's CBC is apologizing for mixing up swimmers Michael Phelps and Ryan Lochte, announcing Lochte as the winner of the 200-meter individual medley final even though Phelps blew away his American teammate and the rest of the competition.
Elliotte Friedman quickly realized his mistake on the air when an on-screen graphic appeared showing Phelps had won. His tone immediately changed from excited to gutted and he corrected himself, saying: ''I apologize, I got my lanes mixed up.''
Friedman apologized further on Twitter, saying: ''I'm sorry everyone. I blew it. No excuses.''
Phelps' win was his fourth gold in Rio and his 22nd overall in the Olympics. Lochte finished fifth, nearly 3 seconds behind Phelps.
Two women will each be seeking a third consecutive gold at the Rio Olympics on Friday.
Tirunesh Dibaba of Ethiopia is competing in the 10,000 meters. She is already considered the greatest female distance runner with her five Olympic medals (three gold) and five world championship golds. The 31-year-old has just finished a yearlong break after the birth of her son.
New Zealand shot putter Valerie Adams, meanwhile, seeks a comeback from elbow and shoulder surgery. She was basically untouchable at major championships from 2007 to 2014, with four world and two Olympic gold medals. But to get gold in Rio, Adams will have to beat China's Gong Lijiao and Christina Schwanitz of Germany, who took over Adams' world title last year.
Gymnast Yuri van Gelder has taken his battle for reinstatement to the Netherlands' Olympic team to a Dutch courtroom, demanding a business class ticket back to Rio just days after he was sent home for a ''grave breach'' of team rules.
The 2005 world champion on the rings was thrown off the team this week after a late-night trip to Rio during which, according to the country's gymnastics association, he drank alcohol before arriving back in the athletes' village early Sunday morning.
Friday's high-stakes court appearance was the latest twist in 33-year-old Van Gelder's turbulent sports career which, alongside his world title, has also featured a ban for cocaine use.
In court documents, Van Gelder says he was denied legal advice or the possibility of appeal.
Few people know the U.S. women's soccer team like former coach Pia Sundhage – but that's not always a good thing for the Americans.
The U.S. women face Sweden on Friday in the quarterfinals of the Rio Olympics soccer tournament – and that means a reunion with Sundhage, who now coaches the Swedish women. Sundhage had led the Americans to Olympic gold in both Beijing and London.
The Brazilian women, meanwhile, have an entire nation of 209 million people rooting for them when they meet Australia on Friday. Led by standout striker Marta, the Brazilians will surely be eager for revenge, since Australia knocked them out of the Women's World Cup last year.
In other women's Olympic soccer matches, China takes on Germany and Canada goes up against France.
Doesn't he have enough Olympic gold medals?
Other Olympic swimmers could be forgiven for thinking that of American superstar Michael Phelps, who already has 22 golds. But the answer is no, he wants another one.
The men's 100 meter butterfly finals are being held Friday, an event in which Phelps holds the world and Olympic records.
Speaking of golds, fellow American Katie Ledecky will be back in the pool for the women's 800 meter freestyle final after setting a new Olympic record in preliminaries Thursday. Ledecky is seeking to sweep the 200, 400 and 800 meter freestyles for the first time since the 1968 Mexico City Games.
Katinka Hosszu of Hungary will be aiming for gold in the women's 200 backstroke and the world's fastest men will compete in the 50 meter free final.
The dominating U.S. basketball teams will be back on the court at the Rio Olympics, with the men hoping to make sure their last contest – a scrambling win against Australia – was just a wobble.
The U.S. men, who play Serbia on Friday, are still the team to beat. In other action, China's men face Australia.
The U.S. women, meanwhile, take on Canada. The three Olympic rookies on the American team have had an impressive start: Elena Delle Donne, Breanna Stewart and Brittney Griner have all taken over parts of games as the U.S. women won their first two Olympic contests in dominating fashion.
Usain Bolt, no slouch himself on the track, says it's going to be hard to pick a favorite in the women's 100 meters at the Rio Olympics.
Olympic track and field events are starting Friday, including preliminary heats in the women's 100 meters.
Five sprinters at Rio have joined the small list of women to crack the 10.8-second mark: Elaine Thompson of Jamaica, Murielle Ahoure of the Ivory Coast and American teammates English Gardner, Tianna Bartoletta and Tori Bowie. Two-time defending Olympic champion Shelly-Ann Fraser-Pryce of the United States is also in the field.
On the men's side, preliminaries start in the 400 meter and 800 meter races. The man to beat in the 800 meters is David Rudisha of Kenya, who holds the world and Olympic records.
In the 400, Rio fans will get a first look at American LaShawn Merritt, South Africa's Wayde van Niekerk and Grenada's Kirani James.
Winning a gold medal in soccer and not worrying about anything else is no longer good enough for Olympic host Brazil.
Brazilian officials say the country now wants to win as many events as it can and finish in the top 10 in the number of overall medals won – a goal some observers believe may be a tall order.
Adriana Bahar of the Brazilian Olympic Committee tells The Associated Press that ''of course, soccer is a passion in Brazil … but now we want to focus on the 41 other disciplines in the Olympics.''
Brazil has won three medals so far – one of each color. But the Rio de Janeiro Olympics have yet to catch on across the sprawling metropolitan area of 12 million. Stadiums for basketball and judo have been full but many other venues have been lightly attended. Golf appeared to have more rules officials than fans on its opening day.
A Brazilian police officer has died after being shot in the head when he and two others working security at the Rio Olympics got lost near a slum and encountered gunfire.
Justice Minister Alexandre de Moraes announced Helio Vieira's death early Friday on his official Facebook page.
The officers from Brazil's national security force were using a GPS device to navigate unfamiliar streets Wednesday afternoon when they took a wrong turn off a highway leading to Rio's international airport. Their truck was sprayed with bullets, shattering the windows.
Viera died late Thursday and the other officers suffered minor injuries.
More than 85,000 security forces have been deployed in Rio for the Olympics, which is double the number of London in 2012.
Several swimmers have been listed with the wrong qualifying times coming into the Rio Olympics – raising even more questions about the way world swimming body FINA is governing the sport.
FINA did correct some mistakes, including that of a Kuwaiti swimmer competing under the IOC flag.
The Guardian newspaper in Britain reported that 17 swimmers from 16 countries still had qualifying times that didn't match their actual results from last year's world championships. All were admitted to the games under the ''universality rule,'' which aims to spread the sport to developing countries that would not otherwise have qualified.
In a statement Friday, FINA said the Olympic competition in Rio was not affected by the wrong times.
FINA did change the qualifying times for several dozen swimmers, as well as some relay times for major teams such as Italy and Hungary. The times determine heats and lane assignments during preliminary heats.
Fiji has its first-ever Olympic medal – and it's gold to boot. Now that's a reason to party.
The Pacific Island nation erupted with joy Friday after its rugby sevens team crushed Britain 43-7 in final in Rio de Janeiro.
In the capital of Suva, fans packed the 15,000-seat National Stadium to watch the Olympic final on a big screen – held Thursday night in Rio but at 10 a.m. Friday back home. Tense at first as they saw their nation on the brink of an historic achievement, fans relaxed and then rejoiced as Fiji ran away with the victory.
Prime Minister Frank Bainimarama, in Rio for the games, told reporters ''rugby has always lifted the spirit and always brought us together. Right now, whatever political party, there's no difference. Everyone is coming together to celebrate.''
He declared a public holiday for Aug. 22, the day after the team returns home.
Chinese officials say a female Chinese swimmer has tested positive for a banned substance at the Rio Olympics – the first competitor in the sport to fail a test at the games.
The Chinese Swimming Association says 18-year-old Chen Xinyi has tested positive for the diuretic hydrochlorothiazide after she finished fourth in the women's 100-meter butterfly Sunday, missing a bronze medal by nine-hundredths of a second. Xinhua, China's official state news agency, reported the story Friday.
Chen was also scheduled to compete Friday in the 50 meter freestyle.
Chen has applied to the International Olympic Committee to have her B sample tested and to get a hearing on the matter, Xinhua said, citing the swimming association, which promised in a statement to ''take this matter seriously.''
