Cameroon has stunned host Ghana by advancing to the African Cup of Nations final with a 1-0 win at Ohene Djan stadium in Accra tonight.

Substitute Alain Nkong scored the only goal of the match as the Indomitable Lions sent the Black Stars' fans home silent.

Ghana will feel aggrieved with the performance of Moroccan referee Abderahim El Arjoune as it lost out in a number of crucial decisions.

But Cameroon will take its own concerns into the Cup of Nations final after defender Andre Bikey was inexplicably sent-off.

Nkong's second-half strike came with just over 20 minutes remaining in the contest, off the back of Ghana's most dominant period in the match.

After a string of free kicks and corners it was a save from goalkeeper Carlos Idriss Kameni that launched a lightning counter-attack.

Kameni fed left-back Timothee Atouba the ball, who found striker Samuel Eto'o in the attacking half.

Eto'o then fed through Nkong, who sprinted into the Ghanaian penalty area and finished one-on-one against Richard Kingson with a clinical strike.

Ghana's best chance to equalise came in the 81st minute when Junior Agogo narrowly headed over a free kick from Sulley Ali Muntari.

Despite being reduced to 10 men in stoppage time Cameroon held out for victory.

After failing to police egregious time wasting from the Cameroonian team, referee El Arjoune did not tolerant a moment of madness from Bikey.

With a convoy of medicos on the field to attend to Rigobert Song, Bikey was given his marching orders for pushing one of the staffers.

Bikey reacted with disgust to the red card, the Accra crowd attempting to hit him with bottles as he left the field.

But it was Ghana who largely got the wrong end of 50-50 foul calls and were not shown how much stoppage time would be played.

Coaches Claude Le Roy of Ghana and Otto Pfister of Cameroon were furious on the sidelines as the fourth official refused to raise his board.

Despite Cameroon milking the best part of 10 minutes off the clock in the second half, barely 4 additional minutes were played after the 90 was complete.

But with time expired it was Cameroon who is through to the final, while Ghana's tour of duty now takes them to Kumasi for the third-place play-off.

Ghana has overcome the sending-off of captain John Mensah to defeat Nigeria 2-1 and book a place in the African Cup of Nations semi-finals.

The Black Stars came back from a goal down as well as a man down to see off its arch rival.

A goal with eight minutes remaining from Junior Agogo gave Ghana victory after the scores were level 1-1 at half time.

Ghana played the last half-hour of the match with 10 men after captain Mensah was issued a straight red card by referee Benouza Mohamed for a challenge on Peter Odemwingie as the last man.

But Ghana had already been outplaying Nigeria before Mensah’s dismissal and after weathering a period of pressure, pressed on to find a winner.

Substitute Haminu Draman beat Obinna Nwaneri on the left flank in a one-on-one to put Sulley Ali Muntari into space on the edge of the area.

Muntari then fired a cross through the six-yard box to an unmarked Agogo at the back post for a tap-in finish.

Nigeria had opened the scoring against the run of play in the first half when Eric Addo bought down Ikechukwu Uche to concede a penalty.

Yakubu Aiyegbeni scored low to the left to give Nigeria a 35th minute lead.

But a Michael Essien header on the stroke of half-time sent Ghana in on level terms. Nigeria’s best chance to re-take the lead in the second half came from the free kick conceded by Mensah’s sending-off.

Goalkeeper Richard Kingson acrobatically saved from Taiwo Taye to keep the scores 1-1.

Despite having a man advantage, Nigeria was unable to make it count after falling behind.

The Super Eagles had half-chances in the final stages but failed to force Kingson into a save.

Ghana now progresses to the semi-final while Nigeria is out.

Ghana has edged Namibia 1-0 in Accra tonight after the visiting side failed to capitalise on its opportunities.

Junior Agogo's bundled back-heel five minutes before half time was the difference for Ghana, who maintains its 100% record to be six points from six.  

But Namibia could not have caught the Black Stars on a better night to cause an upset but could not hit the target when it exploited the Ghana backline.

After Quincy Owusu-Abeyie had threatened repeatedly on the right flank he connected with Agogo whose touch was enough for the ball to cross the line.

Asamoah Gyan started the match partnered with Agogo but was substituted midway through the second half after failing to find his touch.

In the 33rd minute Gyan put the ball over the bar despite his pressure on Namibia goalkeeper Attiel Mbaha forcing the ball free out wide and open the net.

The late goal failed to break Namibia's resolve and it kept its defensive discipline through the second half to make some amends for the 5-1 defeat at the hands of Morocco four days ago.

In the 67th and 68th minutes Namibia twice broke the Ghana defensive line but strikes failed to hit the target - from there any chance of an equaliser was closed down by a Black Stars team happy to waste time.

Michael Essien patrolled the midfield effectively for Ghana through the full match, but the crowd focused more on the inability of Gyan and Agogo to make the most of the chances that fell its way.

''We created a bit of quality but needed a bit of quality,'' a remoseful Namibia coach Arie Schans said after the game.

''We fought everywhere, everytime. We were unlucky our strikers could not score one goal and it meant more pressure when the chances came.''
