Back under way in a raucous Estadio de Bata, not before the referee gets confused about who is supposed to be kicking off. It's Equatorial Guinea, Mr Seechurn.

HALF-TIMEpublished at 21:48 Greenwich Mean Time 31 January 2015
The first half of extra time is over. Tunisia - who let's not forget are ranked 96 places above Equatorial Guinea - have 15 minutes to avoid the mother of all shocks and spoil the hosts' party.
SUBSTITUTIONpublished at 21:45 Greenwich Mean Time 31 January 2015
Tunisia coach Georges Leekens rolls the dice for one final time. Centre-back Mohamed Yakoubi is off, midfielder Youssef Msakni sprints on.

BBC World Service's Piers Edwards in Bata"The fairytale is on and that was a fairytale finish. Inch perfect, right into the top corner and a quality goal from a player who used to be on the books of Real Madrid. This stadium has erupted and how he celebrated. A beautiful finish and Equatorial Guinea are barely 20 minutes away from being one of the top four teams in Africa."

Image source, APOh my lord, Bata is going absolutely mental. Javier Balboa, who has been Equatorial Guinea's best player, bends an absolute peach of a free-kick over the wall and into the top corner. Stunner. The hosts are in dreamland - can they hold on?
Balboa joins Ahmed Akaichi and Thievy Bifouma at the top of the goalscoring charts.

Image source, APA great driving run from Javier Balboa takes him to the edge of the Tunisia area, before he's chopped down by a cynical bodycheck from Aymen Abdennour. The Tunisians incredulously surround the referee but he's right on this occasion - free-kick.

This, by the way, is the fourth successive time that an Afcon quarter-final involving Tunisia has gone to extra time. The Carthage Eagles have lost the last three.

Image source, AP"Have you seen a Tunisia attack in this first half of extra time? No is the simple answer. They are not pressing forward, whether that is because they think Equatorial Guinea will tire or whether they think they will have more success in a penalty shootout I don't know but it is a dangerous game to play."

All Equatorial Guinea. Viera Ellong lines up a shot from range, but it's always rising. Esteban Becker applauds the intent though.

Ivan Bolado skips away from a challenge on the edge of the area and has a shot deflected behind. The corner comes to nothing, but the hosts are pressing, with their substitutes, including Ivan Edu and Bolado, to the fore.

The hosts are on the front foot at the start of extra time. Ivan Edu is almost slipped through the middle, the ball breaks to Ivan Bolado but a desperate block just takes the sting out of his shot. Tunisia need to get going again.

Image source, ReutersAn early free-kick on the right flank for Equatorial Guinea. It's whipped in by Javier Balboa, but comfortably headed clear.

We're back under way. Can Tunisia keep their heads? Can Equatorial Guinea keep the momentum?

We're just getting another look at the penalty incident. There really was nothing in the challenge from Ali Maaloul on Ivan Bolado. Referee Rajindraprasad Seechurn was in a good position, he just got it wrong. And so we have extra time...

Football writer Jonathan Wilson:, external Tunisia, 1-0 up and cruising, have contrived to create an atmosphere in which they could lose, with a ref who's sick of them. Stupidity.

"It has been an extraordinary match. It looked like Tunisia had it all wrapped up and then the referee intervened. Who knows how the next 30 minutes are going to unfold?"
FULL-TIMEpublished at 21:27 Greenwich Mean Time 31 January 2015
What an ending. Equatorial Guinea are improbably, perhaps undeservedly, still alive in this tournament. Tunisia goalkeeper Aymen Mathlouthi lambasts the referee as they walk off, and you can understand his frustration.
