At least nine people were killed and several more injured Saturday in a crush at a soccer stadium in the capital of El Salvador, the National Civil Police (PNC) said on Twitter.

“The first information points to a stampede of fans who tried to enter to watch the match between Alianza and FAS” at the Cuscatlán Stadium, the PNC said.

Salvadoran Health Minister Francisco Alabi said on Twitter that emergency teams had been deployed and the injured were being transferred to local hospitals.

Video provided by the National Civil Police of El Salvador showed multiple ambulances parked outside the stadium and medics rushing to the scene.

Alianza and FAS are two of the most popular soccer teams in the Central American country.
