Host nation Brazil are still searching for their opening win of the Rio 2016 men's football competition after an embarrassing 0-0 draw against Iraq.
Led by Barcelona forward Neymar, Brazil could not find a way past their stubborn Group A rivals in Brasilia.
It is their second goalless draw of the tournament after another blank against South Africa on Thursday.
Elsewhere, Germany drew 3-3 with South Korea thanks to an injury-time free-kick from Arsenal's Serge Gnabry.
Brazil frustrated in Olympic bid
Brazil may have won the World Cup on a record five occasions, but the football-mad nation is desperate to finally claim the one prize that has so far eluded them - Olympic gold.
However, they were jeered by an impatient home crowd of more than 60,000 after failing to beat Iraq.
Brazil had 20 shots at goal, but only managed six on target as the Asian side held on.
"We need to apologise to the fans, to the people," said Brazil coach Rogerio Micale. "As the time passes and we can't score, the anxiety increases, and in this situation it's easier to make mistakes."
Iraq coach Abdulghani Alghazali said: "It's a historic day for Iraq to be able to draw against Brazil at its home. It's a great achievement for Iraqi football."
Denmark top the group with four points after Robert Skov's 69th-minute winner gave them a 1-0 victory over South Africa.
Defending champions Mexico thump Fiji
Defending Olympic champions Mexico recorded a 5-1 win over bottom side Fiji, who conceded eight against South Korea in their opening game.
Erick Gutierrez scored four second-half goals as the Mexicans came from behind to beat the minnows in Salvador.
Fiji held a shock half-time lead thanks to Roy Krishna's header. But Mexico, who drew 2-2 with Germany last time out, were impressive in the second half, particularly Gutierrez.
Mexico are second in Group C, level on four points with South Korea after they were pegged back by Gnabry's late equaliser.
There were seconds remaining when the 21-year-old winger fired in his second of the game via a deflection.
Germany are third in the table on two points.
Portugal on top
In Group D, Portugal continued their 100% start with a 2-1 win over Honduras in Rio.
Alberth Elis gave Honduras a first-minute lead before goals by Tobias Figueiredo and Goncalo Paciencia earned Portugal the points.
They beat Argentina 2-0 in their opening game.
Argentina knocked Algeria out of the Olympic football competition with a 2-1 win over the north African team.
Atletico Madrid's Angel Correa scored and set up Jonathan Calleri's winner. Both teams finished the game with 10 men after Argentina captain Victor Cuesta and Ayoub Abdellaoui were sent off.
Nigeria secure quarter-final spot
Nigeria became the first team to secure a spot in the quarter-finals by beating Sweden 1-0 in Group B.
Sadiq Umar scored a first-half winner for the African side, who have six points from two games.
