Portugal picked up their first win of the 2018 FIFA World Cup as they beat Morocco 1-0 in Group B thanks to an early goal from Cristiano Ronaldo.
The defeat means Morocco are out of the competition as they have lost their opening two fixtures and cannot qualify for the last 16. Meanwhile, Portugal have four points and are in good shape to progress.
Ronaldo also leads the way when it comes to the Golden Boot after scoring his fourth goal of the tournament.
Spain joined Portugal at the top of Group B on four points after a narrow win over Iran. Diego Costa scored the only goal of the game for Fernando Hierro's side.
Uruguay were also winners on Wednesday as they beat Saudi Arabia 1-0 to book their place in the knockout stages. The result means Oscar Tabarez's side and Russia qualify from Group A, while Egypt and Saudi Arabia are eliminated.
Here's a look at all the latest results from Russia and a preview of Thursday's fixtures.

Ronaldo Header Sends Morocco Out
Ronaldo took just four minutes to open the scoring with the game's only goal. The Real Madrid forward dived to meet a Joao Moutinho cross and planted a header past goalkeeper Munir Mohamedi.
The goal was another landmark for Ronaldo as he has now scored more international goals than any other European player, as shown by Match of the Day:
Yet aside from the goal, it was not a vintage display by Ronaldo or Portugal, who were caused problems by a spirited Morocco team.
Nordin Amrabat was a continuous threat down the right flank, but Morocco were guilty of being profligate in front of goal.
Younes Belhanda forced goalkeeper Rui Patricio into a fine one-handed save with a header, while captain Medhi Benatia was guilty of missing a glorious chance to equalise late on.
Football writer Raphael Honigstein summed up their performance:
Portugal threatened only sporadically, although they might have had a second when Ronaldo sent Goncalo Guedes through on goal, but his shot was saved by Munir.
Sports Illustrated's Grant Wahl offered his view of Portugal's campaign:
Morocco's exit feels cruel as they were unfortunate to lose, but they simply lacked a finishing touch. Portugal look set to progress but may need to offer more than just Ronaldo to win the World Cup.
Suarez Sends Uruguay Through
Saudi Arabia are also out of the tournament after a narrow defeat to Uruguay. Striker Luis Suarez scored the only goal of the game as he stroked home after goalkeeper Mohammed Al Owais misjudged a cross into the box.
The Barcelona striker was making his 100th international appearance, and the goal also ensured he made history:
Saudi Arabia lost 5-0 to Russia on the opening day but put in a far stronger display although they were unable to score their first goal of the tournament.
Uruguay were far from impressive but did enough to win, and they will be happy with another three points and another clean sheet. They may lack flair but are strong defensively and look tough to beat.
Spain Survive Iran Scare
Spain were given a tough test by Iran but managed to hold on for a vital win. A hard-fought first half saw few chances on goal as Iran defended diligently. Dermot Corrigan at ESPN FC highlighted Spain's chances:
Costa scored eight minutes into the second half but required a good dose of luck to break the deadlock. Ramin Rezaeian tried to tackle the striker, but the ball hit Costa and deflected past goalkeeper Alireza Beiranvand.
Iran kept going and thought they had equalised when Saeid Ezatolahi fired home from close range. There were wild celebrations from the Iranians but the goal was ruled out for offside by VAR.
Carlos Queiroz's side had a late chance as Vahid Amiri nutmegged Gerard Pique and then found Mehdi Taremi but he could only head over.
ITV Football showed how the group stands after the second round of games:
Despite the result it was an impressive performance by Iran and they remain in contention in Group B. The team finish their group campaign against Portugal on Monday, while Spain will take on Morocco.
