At least 17 people have been killed in a stampede at a football stadium in the northern Angolan city of Uige, local officials say. Hundreds more were reported to have been injured when supporters stormed the gates after failing to gain entry. Some of those who fell became trapped and suffocated at the venue on Friday, a medical official said. Witnesses said the crowd trying to gain access would have taken the stadium past its 8,000 capacity. Santa Rita de Cassia were hosting Recreativo do Libolo in a first division league match.
