Equatorial Guinea earned a shock win over Algeria with the result putting the Africa Cup of Nations holders on the brink of elimination in Cameroon.

Algeria headed into the Group E match at the Japoma Stadium with a 35-match unbeaten run, two shy of the world record set by Italy last year.

The Algerian team were hoping to improve on their goalless draw with Sierra Leone in their opening fixture.

Algeria thought they had taken the lead midway through the first half through Baghdad Bounedjah, only for the goal to be ruled out for an earlier offside.

Esteban Obiang gave Equatorial Guinea a surprise lead in the 70th minute, connecting at the far post after a corner was flicked on.

Algeria saw a second goal ruled out for offside after Youcef Belaili found the net, with Equatorial Guinea holding on to clinch a 1-0 win and their first three points of the group stage.

The result leaves Algeria bottom of the group on one point, with their final game coming against the Ivory Coast.

Ivory Coast lead the standings on four points after a dramatic 2-2 draw with Sierra Leone, who are third on two points.

Sierra Leone twice came from behind at the Japoma Stadium.

Ivory Coast forward Sebastien Haller gave his side a 25th minute lead in the tie, with the pre-match favourites having earlier seen a penalty from midfielder Franck Kessie saved by Mohamed Nbalie Kamara.

Sierra Leone levelled early in the second half with Musa Noah Kamara, who currently does not have a club team, firing a powerful left-footed effort beyond the dive of Badra Sangare.

Nicolas Pepe put the Ivory Coast back in front with a well-placed effort in the 65th minute, before a dramatic conclusion to the contest.

Sangare appeared to have caught a header uncontested in the final minute, only for the Ivory Coast goalkeeper to spill the ball on landing.

The loose ball was passed to Alhadji Kamara, with the Sierra Leone forward tapping into the empty net from close range.

Sangare was stretchered off after the incident, with captain Serge Aurier forced to take over in goal for the final seconds of the contest.

Tunisia secured their first win of the Africa Cup of Nations by brushing aside Mauritania in Group F.

Tunisia had been left angered by the conclusion of their opening match, where Zambian referee Janny Sikazwe controversially blew the full time whistle early in their 1-0 loss to Mali.

The Tunisian team responded impressively in their second Group F match, taking a 2-0 lead against Mauritania after eight minutes.

Hamza Mathlouthi fired a right-foot shot into the far corner after four minutes at the Limbe Stadium in Cameroon, before a composed close-range finish from Wahbi Khazri to double the advantage.

Khazri scored the pick of the goals after half-time, with the midfielder allowing the ball to run to Ghaylène Chaalali before firing into the bottom corner after running onto his team mate’s pass.

Khazri then provided the assist for Tunisia’s fourth goal two minutes later, with Seifeddine Jaziri finishing the scoring in the 66th minute.

Tunisia were left settling for a 4-0 victory after Youssef Msakni missed a late penalty.

Tunisia remain third in the Group F standings after Mali and Gambia played out a 1-1 draw, having won their opening fixtures.

Mali appeared on course for a second consecutive win after Ibrahima Kone scored a 79th minute penalty, after Yves Bissouma was fouled in the area.

Gambia, who had hit the woodwork twice in the first half, were given the chance to level in added time when Bissouma was adjudged to have handled in Mali’s penalty area after a Video Assistant Review.

Musa Barrow converted the subsequent penalty to earn a point for Gambia, with the lowest ranked team at the tournament now looking well-placed to reach the knockout stage.
