The riot broke out in connection with a disputed penalty situation when angry supporters stormed the pitch.
Local media describe the start of the tumult as the penalty situation infuriating supporters, who began throwing stones. Then, security guards responded by using tear gas.
According to AFP, at least 56 people have been killed and several have been taken to hospital.
Bodies are lined up as far as the eye can see inside the hospital. Others are lying on the floor in the corridors. The morgue is full, says an anonymous doctor, according to AP.
"Beyond all limits"
Former Östersund goalkeeper Aly Keita is a national team player for Guinea and reacts with dismay over the incident.
It's a great tragedy and something that should never happen. My thoughts go to those who have passed away, says Keita to Expressen and continues:
It's hard to describe, but football there is a matter of life and death for fans. But this is beyond all limits and something that should never happen.
Keita has played 24 A-international matches for Guinea. He has represented the country in three African championships and in World Championship qualifying.
"Passion that is crazy"
The fans in Guinea have a passion that is crazy, but football is not about violence or anything offensive, so it destroys the sport. Football is a sport that brings everyone together, it doesn't matter where you come from or how rich or poor you are, says he to Expressen.
According to local media, the final match between Labe and Nzérékoré was part of a local tournament organized as a tribute to Guinea's junta leader Mamadi Doumbouya, who took power in a coup in September 2021.
Doumbouya claimed at the takeover that he "prevented the country from sliding into chaos and would make up for the previous government's broken promises". The junta leader has, however, received strong criticism for not being able to live up to his promises and for his way of governing the country.
