Stage Collapses at Campaign Rally in Mexico, Killing at Least 4

A stage in northern Mexico where a presidential candidate was campaigning collapsed after a gust of wind blew through the area on Wednesday night, leaving at least four people dead and at least 15 others injured, officials said.

The stage collapsed in a suburb of Monterrey, in the state of Nuevo León, during an event attended by the progressive candidate Jorge Álvarez Máynez and other members of the Citizens’ Movement party. The collapse was caused by strong wind, President Andrés Manuel López Obrador of Mexico said on social media.

Mr. Álvarez Máynez said on social media that he was “fine” after the collapse, in the city of San Pedro Garza García and that he had been communicating with the state authorities to determine what had happened.

Samuel García, the governor of Nuevo León, told people in the state to take cover from the storm.

“We’re witnessing electric storms. Very strong winds and heavy rain is expected for the next two hours,” he said in a video message. “There’s already been a tragedy.”

This is a developing story.
