90+2 min: There is an understandable - indeed, perfectly sensible - lack of intensity to the play now. The priority seems to be to just wrap up this game formally and then get the hell out of there.

90 min: The official clock in the corner of the TV screen said play actually resumed in the 90th minute. Even some time seems to have got lost during the forced break.

86 min: It’s on! After a powwow of about one minute, the ref walks over, drops the ball and the game is back on.

86 min: The plot thickens. It now seems that play will not resume. The ref and players seemed poised to perform the dropped back for about 60 seconds, but then the ref was beckoned over to the sidelines by chaps in suits - presumably CAF officials - and agitated discussions are taking place. It is not apparent who is in charge, nor what will happen.

86 min: Well this is a turn-up. After an interlude of about half an hour, play is resuming with a dropped ball. It’s not clear what is happening in the stands, but reports suggest that the trouble-makers have been driven outside. Quite what is going on out there - and what will go on out here later - is even less clear.

The players, ref and assistants are still standing in the middle of the pitch. I don’t know whether that means that they still hope that the match can resume or simply that they cannot find a safe route to the dressing rooms.

According to various reports, trouble is now brewing outside the stadium: many people of dubious intent have apparently gathered near the exists and are suspected to be waiting to ambush Ghanaian fans. I hope those reports were wrong, or that sufficient security forces are in place to prevent this deteriorating...

From what the TV cameras are showing, many of the fans have left the stadium. But apparently not the one causing trouble, judging by the way the Ghanaian fans who were attacked are still huddling behind the goal at one hand, clearly not prepared to return to where they had been. A helicopter is still hovering over the pitch, though stewards seem to be waving the home players back on to the pitch.

Most of the Equatoguinean squad are on the running track around the pitch at the end of the ground where the trouble is, pleading with fans to calm down.

There is a kerfuffle on the pitch now as several Equatoguinean players surround a couple of CAF officials in much the same way that they kept surrounding the ref earlier on. They are evidently unhappy about a decision, which suggests the organisers may have resolved to abandon the game. But maybe not. Nothing is clear at the moment.

The cameras still are not showing anything other than the players and officials standing and hoping. But there are sounds of helicopters in the sky, which suggests a significant security is under way operation to restore order. The fault for this lies, of course, with the people throwing stuff and perpetrating whatever other sort of mayhem we are not being shown. But the Equatorial Guinea players cannot claim to have shown a good example of sportsmanship, having fouled, acted and bickered ever since it became clear they were not good enough to win the match. It’s a real pity how this is ending.

Players and officials are still standing on the pitch. They are obviously hoping they can play out the remaining six minutes or so but it is hard to know how likely that is, as the cameras are not showing what is going on at the end of the stadium where the trouble seemed to be.

84 min: Oh dear. This is what we feared: the referee has picked up the ball and asked the police to restore order as fans spill on to the edge of one end of the pitch. There are suggestions that they are Ghanaian fans seeking safety after being bombarded by bottles and other objects, but the situation is not at all clear.

82 min: Acheampong ducks to avoid some hurled object as he waits on the sideline before coming on in place of Andre Ayew.

80 min: After the ball breaks loose at the edge of the Ghanaian box, Doualla attempts a reprise of Yaya Touré stonking goal for Ivory Coast last night. But it’s poor cover version, ballooning into the stand.

78 min: There have been five yellow cards so far and that is because the ref has been quite lenient: Mbele, for instance, could have had at least a couple by now, including for a brutal lunge at Appiah just now. Ghana players will have to keep their wits about them to avoid injury here if their hosts’ mood darkens...

70 min: Freekick to Ghana wide on the left after Kike tugs back Appiah. A bottle is chucked from the crowd at Wakaso as he tries to take it. Eventually the debris is cleared from the pitch and he sends a weak delivery to the first defender.

68 min: It is not clear which Equatorial Guinea are pursuing more eagerly: a goal, or a red card for Ghana? Cringe-worthy acting from them now almost every time there is physical contact.

66 min: Andre Ayew booked for a mistimed but entirely well-intentioned tackle on Kike, who goes rolling as if pushed down a hill.

63 min: Lovely exchange between Jordan Ayew and Atsu, before Mbele makes a critical interception to deprive Appiah of the opportunity to tap into the net from close range.

62 min: Rahmann joins in a Ghana attack and picks out Jordan Ayew with a good low ball from the left. But Ayew mis-controls and gives Equatorial Guinea a chance to romp forward in that helter-skelter way of theirs.

60 min: Becker has introduced the giant striker Raul Fabiani instead of defender Evuy as he seeks to stimulate a comeback.

58 min: Ghana are regularly threatening on the counter-attack as the hosts send more players forward in search of a route back into the game. Ovono has to rush off his line again to deny a forward, and his intervention is well-timed.

57 min: Wakaso, for the second time in the game, is caught in possession just outside his own box. Suddenly Equatorial Guinea have a chance to revive the game, but Balboa dabbed a feeble shot way wide after being teed up by Nsue.

55 min: Mensah heads a freekick back across the face of goal and Andre Ayew has a simple opportunity to nod in from close range - but he fails to anticipate properly and flicks his header wide!

52 min: Ghana come roaring forward on the counter-attack after Iban Edu botches a corner. Wakaso has a variety of options and Ghana should score a third ... but Wakaso overhits an easy pass, donking it back to the keeper.

51 min: Nsue tries to lead an Equatoguinean fightback in the right sense, careering down the wing and curling in a wicked cross that causes momentary bother in the Ghanaian defence before it’s put behind for a corner.

49 min: You wouldn’t like to speculate about what will happen if Ghana score a third here - but Jordan Ayew is doing his best to find out. He raced into the box and had a shot from a tight angle put out for a corner. The hosts clear it well, but Ghana come back at them again...

47 min: The atmosphere in the ground is very tense ... but Ghanaian goalkeeper Razak appears to have brought protection with him for the second half: he’s just stationed plastic Spider-man figurine. beside his goal.

46 min: The teams are back on the pitch. Let’s hope they get to finish the game. This tweet from Jonathan Wilson gives an idea of how the atmosphere seems to be degenerating :

It seems that Equatorial Guinean fans have lost their heads even more than their players: Ghana cannot go into the dressing room at half-time because there is a cascade of missiles being hurled from the stands. The Black Stars are standing out of range in the middle of the pitch.

43 min: Equatorial Guinea are feeling very put upon here: they took kick-off quickly and began racing down the other end, only to be called back by the referee, who hadn’t indicated that play could resume - which is a good thing for Ghana, as most of their players were still off the pitch celebrating their goal! The home players converge on the ref to demand an explanation as to why they should have to wait for their opponents to stop whooping and dancing, but the official tells them to pipe down. You get the feeling that CAF will be receiving another angrily-worded letter in the near future ...

PENALTY! Ovono embarked on another charge off his line but this time he has mistimed it and brought down Appiah!

36 min: On the evidence so far you can see the effect that Esteban Becker has had on his team, but not the effect that Avram Grant has had on his: Ghana look disjointed and unimaginative. OK, some may that is Grant effect, but that’s a cheap shot. But we’ll take what we can get in terms of shots at the moment - there hasn’t been any decent ones on the pitch for a while.

33 min: Boye boots the ball straight into touch under minimal pressure, encapsulating Ghana’s lack of composure and accuracy. In truth, the game has been high on energy but sadly low on quality so far.

30 min: Wakaso pings an early ball to Andre Ayew - that’s a recurring tactic - and the Marseille man takes it down nicely, but is then crowded out, as he has been virtually every time he’s got the ball so far.

28 min: Jordan Ayew tries to shuffle his way into the box, then turns back and feeds Wakaso, who lays it back for Atsu to have a pop from 20 yards. His low skimmer whizzes wide.

26 min: Ghana’s play is becoming increasingly disjointed. It’s looking like this is going to be another match where they will need individual ingenuity to overcome systemic ineffectiveness. Equatorial Guinea, meanwhile, are gaining in confidence and menace.

23 min: What’s this? A bewildering decision by the referee outrages the hosts! Iban Edu, in fact, jumped into the air in fury after being called back for a so-called foul after nicking the ball of Wakaso. Three other Equatoguineans charge towards the ref to express their dismay, too. Nope, definitely not a homer this ref.

21 min: Jordan Ayew is pulled back for offside again. Perhaps it’s time someone pulled him aside and explained the offside law? You’d think he’d have heard mention of it before given his background.

20 min: Negligent defending by Ghana is almost punished as Nsue strains to get his head on a freekick that is allowed to bounce in the visitors’ box. But the Middlesbrough man can’t direct his shot on target.

18 min: Wakaso rightly booked for shunting over Kike as the hosts tried to launch another quick counter-attack. Not a tackle likely to cause physical harm, but definitely one that should be punished severely as it was a deliberate act of sabotage on a promising move.

17 min: For the second time in the game Ovono hurtles off his line to clear the danger, this time throwing himself at the ball as Wakaso and A Ayew bore down on it.

15 min: Ghana’s play has not been precise enough to pick a way through an Equatoguinean side who are full of vibrancy: and their energy will not necessarily abate, as we saw in previous games.

13 min: Kike sends the decibels soaring with a jinking run down the right, and he’s unlucky not to be given a freekick after appearing to be shoved over as he tried to enter the Ghanaian box. No risk of the ref being seen as a homer, as this point.

11 min: Afful flies down the right and curls a delicious ball into the centre. Appiah makes a stab for it but can’t connect due to pressure from the home defence.

9 min: Ghana create a clear shooting chance for the first time, Jordan Ayew teeing up his brother Andre. But Zarandona stretched out a leg to poke the ball away with a brilliant tackle just as the elder Ayew tried to fire into the net from 14 yards.

7 min: After a long bout of ineffective Ghana possession, Equatorial Guinean gave a demonstration of the danger they carry. They intercepted a sloppy Ghanaian pass and then hurtled forward at jarring speed. If the cross to Iban Edu had been better placed, Ghan acould have been punished. BUt it went behind the midfielder and ran to Balboa, whose mis-hit his acrobatic attempted half-volley.

4 min: Ghana are trying to establish their superiority early on, controlling possession and forcing the hosts to run around after them.

2 min: There is no lack of vim from the hosts early doors but their yearning to impress has already led to some ill-timed challenges. From one freekick Wakaso launches the ball into the box and Ovono has to scamper off his line to punch it clear before Appiah can get his head to it.

1 min: It’s on!

Stumble? Nah, Robert Mugabe was just rehearsing his goal-scoring celebration ...

Ghana’s anthem booms out around the ground and their players stand to their attention with their hands on their hearts. That is followed by the Equatoguinean tune, which is accompanied lustily by the vast majority of the people in the stadium, creating a noise befitting the National Thunder.

So as you can see from the line-ups, Gyan is not fit enough to play, meaning Kewsi Appiah starts instead. Can he crown his improbable rise from League Two by scoring the goal that puts his country into the final?
