An investigation is under way after an African Nations Cup qualifying match between Senegal and Ivory Coast descended into rioting.

The referee halted the game with about 14 minutes to go after Senegalese fans lit fires and threw objects onto the pitch in Dakar.

They were angry as their team failed to impress against Ivory Coast and after they went two-nil down, the trouble heightened.

Riot police were called in and fired teargas inside the packed stadium to try to keep order. Ivorian fans had to be protected in a huddle on the pitch while security forces escorted the players out of the ground.

Five or six people were injured and carried off on stretchers.

The two-nil scoreline is likely to stand which would mean Ivory Coast progess through to the next stage of the competition while Senegal are knocked out.
