At least twelve people have died after a crush at a football stadium in El Salvador's capital, San Salvador.

The incident occurred during a match between local team Alianza and the Santa Ana-based team Fas at Cuscatlán Stadium. The match was subsequently suspended.

He said "everyone" will be investigated, including teams, managers, stadium officials, the league and the federation.

"Whoever the culprits are, they will not go unpunished," he said in comments posted to Twitter by his press secretary.

The disaster reportedly occurred after a large number of fans tried to enter the venue after the gates had been closed.

Officials believe some fans had been sold fake tickets, and said that an investigation was under way.

Footage shared by local media appeared to show fans attempting to pull down barricades at the stadium's entrance.

A livestream of the match posted on YouTube shows the match being suspended after an apparent commotion in the stands. People are later seen being carried away by emergency services on stretchers.

Fans are also seen waving their shirts at people on the ground to try and cool them down.

Officials also said that 90 people were being given medical attention, and that men, women and children had been treated for "multiple traumas".
