Angola's sports ministry has said it regrets the death of five football fans at an African Champions League tie on Saturday evening.

The incident happened in Luanda as Primeiro de Agosto drew 0-0 with DR Congo's TP Mazembe in the first leg of a Champions League quarter-final.

The ministry said in a statement it regretted the deaths and that the seven injured people had already been discharged from hospital.

It added that a commission of inquiry will be set up to investigate the causes of the incident.

Witnesses said the stampede happened after fans found the gates to the Estádio 11 de Novembro stadium shut after the match.

When police opened the gates, fans rushed out and some were trampled under police horses.
