A stampede at a soccer stadium in El Salvador on Saturday left at least nine people dead and hundreds of others injured, officials said.
The deadly crush happened as fans reportedly pushed through an access gate during a Salvadoran league quarterfinal match between clubs Alianza and FAS at Monumental stadium in Cuscatlan.
The National Civil Police confirmed on Twitter that there were at least nine deaths and that two of the injured were in critical condition.
Carlos Fuentes, spokesman for the first aid group Rescue Commandos, also confirmed the deaths.
"We can confirm nine dead — seven men and two women — and we attended to more than 500 people, and more than 100 were transported to hospitals, some of them were serious," Fuentes told The Associated Press.
A commotion in the stands began just 16 minutes into the match, with fans waving frantically as others carried the injured out of a tunnel and down to the pitch. The match was subsequently suspended.
A volunteer with a first aid group described the chaos to journalists as an "avalanche" of fans who apparently burst through a gate into the stadium.
The aftermath of the stampede was broadcast on live television.
Dozens of fans were seen receiving medical treatment on the field as the fans who escaped the crush stood on the pitch waving shirts over those apparently lying unconscious on the grass.
El Salvador President Nayib Bukele tweeted that there will be an "exhaustive investigation" of the disaster.
"Everyone will be investigated: teams, managers, stadium, ticket office, league, federation, etc," Bukele wrote. "Whoever the culprits are, they will not go unpunished."
The Salvadoran Soccer Federation said in a statement that it regretted what had happened and voiced support for the victims' families.
Cuscatlan is about 25 miles (41 kilometers) northeast of San Salvador.
