Tanzania earned one of the fastest penalties in football history when Simon Msuva was fouled after just four seconds against Madagascar, with the resulting spot-kick converted on their way to a 3-2 win.

Msuva latched onto a hopeful punt forward after Tanzania kicked off before being felled on the edge of the box by onrushing Madagascar goalkeeper Melvin Adrien.

With five seconds on the clock, the referee pointed to the spot with Erasto Edward Nyoni converting a minute later to give his side an early lead.

Tanzania's penalty could well be the fastest-awarded penalty of all time, although this has yet to be officially confirmed.

In 2014, Montenegro were given a penalty after just 10 seconds in an international friendly against Ghana while there have also been sub-10-second penalty awards in club football.

The hosts doubled their lead before the half-hour through Novatus Dismas Miroshi, but Madagascar rallied to make it 2-2 at half-time thanks to Njiva Rakotomarimalala and Thomas Fontaine.

Shortly after the break, Feisal Salum Abdallah sealed the points to move Tanzania top of Group J with four points, ahead of Benin on goal difference.

Day of penalties

Tunisia became the first team to gain a maximum six points from their opening games when winning 2-0 in Zambia.

Just as he did in last week's win over Equatorial Guinea, Carthage Eagles skipper Wabhi Khazri scored from the spot, after just nine minutes, before Anis Ben Slimane doubled the lead in stoppage time.

In the other game in Group B, Equatorial Guinea beat Mauritania 1-0 as captain Iban Salvador converted another penalty on the the hour mark.

The results mean Tunisia are three points clear of both Zambia and Equatorial Guinea, with Mauritania pointless after two games.

Senegal also made it two wins from two as they beat hosts Congo Brazzaville 3-1 in Group H.

The visitors took the lead after 26 minutes through Boulaye Dia before Congo equalised on the stroke of half-time as Silvere Ganvoula beat Chelsea goalkeeper Edouard Mendy with a fiercely-struck penalty.

Liverpool and Senegal's Sadio Mane

Senegal retook the lead through Watford's Ismaila Sarr in the 83rd minute before Congo keeper Christoffer Maoumbi felled Sadio Mane moments later, enabling the Liverpool forward to now score from the 12-yard mark.

After two rounds of qualifying, Senegal have six points, Namibia four, Congo one while Togo are seeking their first.

Elsewhere, a much-changed Nigeria side - for whom captain Ahmed Musa was winning his 100th cap - needed two bits of poor defending from hosts Cape Verde to come from behind to win 2-1 in Group C.

The Blue Sharks took the lead after 19 minutes through Swiss-born Dylan Tavares before Napoli's Victor Osimhen was on hand to turn the ball home after keeper Vozinha did well to prevent an own goal from Kelvin Pires' sliced clearance.

In the 75th minute, Nigeria benefited again from poor defence by Cape Verde as Kenny Rocha scored an extraordinary own goal when inadvertently lobbing Vozinha from 35 yards out.

After two matches, Nigeria have maximum points, Liberia three while Cape Verde and CAR have a point each.

Earlier on Tuesday, Malawi moved just a point behind Group D leaders Ivory Coast after beating Mozambique 1-0.

Richard Mbulu profited from a calamitous 30-yard back-pass after nine minutes which presented him with an open goal after the ball rebounded off the post.

Malawi and Cameroon now have three points in one of African World Cup qualifying's hardest groups, with the Ivorians on four and Mozambique pointless.

In Group G, Ethiopia earned their first win when beating Zimbabwe 1-0 thanks to a 94th-minute penalty from Aschalew Tamene.

The win takes the Ethiopians to three points, one behind South Africa who beat Ghana 1-0 in Johannesburg on Monday.

The Black Stars also have three points, two more than bottom side Zimbabwe.

Only the winners of Africa's ten qualifying groups qualify for the play-offs next March, when the continent's five finalists for next year's World Cup will be known.
