SAN PEDRO GARZA GARCIA, Mexico (AP) — At least nine people are dead and 63 more injured after the collapse of a stage during a campaign rally in the northern Mexican state of Nuevo Leon. The state’s governor confirmed the tragedy and said among the dead was a child. A strong gust of wind caused the stage to collapse during an event attended by presidential long-shot candidate Jorge Álvarez Máynez. Videos of the dramatic collapse were posted to social media Wednesday night. The clips showed people screaming and running away, and later climbing out from under metal polls. Afterward, soldiers, police and other officials roamed the grounds of the park where the event took place.
