In northern Mexico, at least nine people were killed and 60 people were injured in a stage collapse during a campaign rally. A strong gust of wind knocked everything over during an event that was attended by a presidential longshot candidate.

Videos of the dramatic collapse posted to social media last night show people screaming and running away and then climbing out from under metal poles. Mexico's current president says he's sending a "hug" to all who were injured.

Campaign season in Mexico has been plagued by the killings of about two dozen candidates. A mayoral candidate and five other people were killed just last week when gunmen opened fire at a campaign rally in southern Mexico.
