Twelve people have been killed in a stampede at an El Salvador stadium where soccer fans had gathered to watch a local tournament, police said.
Authorities said initial reports pointed to a crush of fans who tried to enter Cuscatlan Stadium in the Central American country's capital San Salvador to watch a match between teams Alianza and FAS on Saturday.
The match was suspended as emergency personnel evacuated people from the stadium, where hundreds of police officers and soldiers gathered as ambulance sirens wailed.
"Preliminarily, we have a negative result of 12 victims, nine who are here in the stadium and three more that we have been informed are in different hospital centres," National Civil Police (PNC) director Mauricio Arriaza told reporters.
"Salvadoran soccer is in mourning," Arriaza said.
Health Minister Francisco Alabi said the country's hospital network was "providing medical care to all patients."
Interior Minister Juan Carlos Bidegain said the civil protection service's first responders were on the scene.
Carlos Fuentes, spokesman for the emergency services group Comandos de Salvamento, said they were treating more than 500 people.
About 100 people in serious condition were taken to hospital, with some showing signs of asphyxia and other types of trauma, Fuentes said.
The stampede apparently started after a stadium gate fell, causing people to crowd together, he said.
El Salvador's President Nayib Bukele said the PNC and the Attorney General's Office would investigate the incident and those responsible would be punished.
"Everyone will be investigated: teams, managers, stadium, box office, league, federation," Bukele said on Twitter, adding "whoever the culprits are, they will not go unpunished."
The Salvadoran Football Federation (Fesfut) said in a statement it "deeply regrets" the events that occurred at the stadium and "expresses its solidarity" with the families of those "affected and killed."
"Fesfut will immediately request a report of what happened and will communicate the relevant information as soon as possible," it said.
The tragedy comes seven months after 135 people, including more than 40 children, were killed in a stampede following a football match in Malang, Indonesia.
