Sadio Mane slotted the decisive penalty to send Senegal to the World Cup finals while his Liverpool team-mate Mohamed Salah suffered shoot-out heartbreak for Egypt.

Mane's spot-kick concluded a dramatic second leg in Diamniadio after Hamdi Fathi's fourth-minute own goal hauled the hosts level following Egypt's 1-0 win in Cairo on Friday night.

The result was a repeat of the Africa Cup of Nations final two months ago when Mane again scored the winning penalty against the same opponents.

Senegal dominated most of the proceedings and Egypt were indebted to keeper Mohamed El Shenawy who produced a series of stunning saves to deny Pape Abdou Cisse and Ismaila Sarr in extra-time.

Salah blazed Egypt's first penalty over the bar and after both sides contrived to miss their first four spot-kicks combined, it fell to Mane to seal his side's passage to Qatar.

Karl Toko Ekambi scored a 124th-minute winner as Cameroon sensationally booked their place at the World Cup with a 2-1 victory over hosts Algeria in their play-off tie at the Stade Mustapha Tchaker.

Algeria looked to have booked their place when Ahmed Touba netted with three minutes remaining at the end of extra-time, but as Cameroon pushed everyone forward for the final play of the game, Toko Ekambi latched onto a loose ball to net a most unlikely winner.

The victory on the away goals rule seals an eighth World Cup finals appearance for the Indomitable Lions and follows a 1-0 win for Algeria in the first leg on Friday that left them heavy favourites to advance.

Tunisia's players celebrate qualifying

It seals a disastrous few months for the north African side who were dumped out of the Africa Cup of Nations finals, ironically played in Cameroon, in the first round in January as they gave up the title they won in 2019.

Thomas Partey's early goal saw Ghana also qualify for the finals after a 1-1 draw with Nigeria in Abuja, which proved enough to send the Ghanaians through on the away goals rule.

Tunisia qualified for a sixth World Cup appearance after a 0-0 draw at home to Mali ensured their place at the tournament in Qatar with a 1-0 aggregate triumph.

Mali, who have never previously qualified, were much more enterprising but failed to break down a typically tight Tunisia defence, as the hosts held onto their advantage from last Friday's first leg in Bamako.

The north Africans benefitted from a horror own goal in Mali where defender Moussa Sissako contrived to turn the ball into his own net in the first half of the first leg and then get himself sent off only four minutes later.

Morocco will also contest their sixth World Cup after Azzedine Ounahi netted a double as they overcame first-half injuries to beat the DR Congo 4-1 in the second leg of their playoff for a 5-2 aggregate win.

Tarik Tissuoadali and Achraf Hakimi scored the other goals for Morocco, who were 2-0 up at halftime despite losing defender Jawad El Yamiq after six minutes to a muscle injury and having to take off goalkeeper Yassine Bounou, suffering from concussion after twice being hit on the head in aerial duels, in the 43rd.

Substitute Ben Malongo netted a consolation for the Congolese with a shot on the turn from the edge of the penalty box that was the pick of the night’s efforts.

In the final round of qualifiers in Asia, United Arab Emirates' booked a play-off clash with Australia in Doha on 7 June after sealing third place in Group A after a 1-0 over already-qualified South Korea.

The winner of the play-off will then face the fifth-placed team in the South American qualifiers for a place at the final tournament in Qatar.

South Korea, Japan, Saudi Arabia and Iran had already qualified for the World Cup.
