VIDEO: Mexico stage collapse kills 9 at election rally

At least nine people have been killed while over 50 people have been injured after a massive stage collapsed and came down crashing on the crowd during an election campaign rally in Mexico on Wednesday.

The horrific scenes followed as high winds tore apart the large, concert-style structure, scattering politicians and attendees in San Pedro Garza Garcia, Nuevo Leon, USA Today reported.

Samuel Garcia, the state's governor, revealed on social media that the rally was for the Citizens' Movement party and the victims included eight adults and one child, with three people in surgery at a hospital.

Video of the accident showed the sudden collapse of the structure, falling forward into the crowd.

"I've never experienced something so sudden," Jorge Alvarez Maynez, the presidential candidate for the Citizens' Movement party, told reporters, referring to how quickly the wind picked up before the stage collapsed.

After the incident, Alvarez Maynez announced the suspension of his campaign activities and hoped authorities investigate the incident, requesting transparency in the process.

Members of Mexico's national guard and army were on the scene to provide support, Interior Minister Luisa Alcalde said on social media.

Meanwhile, Garcia warned residents to stay indoors amid strong thunderstorms in the area.

Alvarez Maynez is polling in third place in Mexico's presidential election set for June 2. He trails far behind ruling party candidate Claudia Sheinbaum and second-place Xochitl Galvez, who represents a broad opposition coalition.
