Two people have been killed and more than a dozen others injured in a stampede at a football match in South Africa. The stampede happened at the gates of Johannesburg’s FNB Stadium during a pre-season game between rivals Kaizer Chiefs and Orlando Pirates.

Michael Sun, a public safety official, said the stampede is believed to have been caused by people trying to sell or present fake tickets at a stadium gate. He added that paramedics are in attendance.

Match sponsors Carling Black Label said one fan was critically injured and another 16 spectators suffered minor injuries. The brewer said it was “saddened by the fatalities” from the crush caused by “a number of people who attempted to push through the stadium gates”. Tickets were sold out two weeks before the game, although local media reports suggested fake tickets had gone on sale.
