An incident ahead of a local football derby in the Peruvian capital Lima has left one fan dead and dozens injured. Officials are investigating the cause. Initial reports suggested parts of the stadium's wall and structure had collapsed, which has since been disputed. Confirming the death, Peruvian Health Minister Juan Carlos Velasco Guerrero told media at a Lima hospital that 47 people were hurt - three of whom are in a critical condition. Hundreds had gathered around Alejandro Villanueva Stadium wearing football shirts and waving flags of the home team, Alianza Lima, ahead of a match against local rivals Universitario de Deportes. Fire Chief Marcos Pajuelo told reporters that the structure of the southern stands appeared to be in good condition, stating, There are no collapsed walls or sections fallen into the pit. Saturday night's match will still go ahead as planned, the football league said. Earlier, the interior ministry published on X that 40 firefighters responded to an emergency at the stadium involving people trapped in a structure. However, Alianza Lima later published a statement on X that said: According to the preliminary information available, the incident is not related to the collapse of walls or structural facilities of the sports complex. The Peruvian Professional Football League's statement highlighted its commitment to the safety and well-being of all attendees at sporting events.
