At least five people died on Wednesday evening in the northern Mexican state of Nuevo Leon after a stage collapsed at a campaign event for the Citizens’ Movement party, authorities said.

Around 50 people were injured, Nuevo Leon Governor Samuel Garcia said on social media, while the director of Mexico’s social security institute reported that dozens were being treated at local clinics.

Garcia said five people died in the accident. Local mayor Miguel Trevino, however, said six people had been reported killed.
