Mexican President Claudia Sheinbaum decries shooting at Irapuato festival as ‘deplorable’ and promises investigation.

A gun attack during a religious celebration in central Mexico has left 11 people dead and at least 20 others injured in violence-plagued Guanajuato state, local officials have confirmed.

The shooting erupted Tuesday night in the city of Irapuato, authorities said on Wednesday, during festivities marking the Nativity of John the Baptist. Witnesses described terrible scenes of panic and chaos as partygoers fled the gunfire.

“It was chaos. People put the wounded into their cars and rushed to hospital to try to save them,” one witness told the news agency AFP, speaking anonymously due to safety concerns.

Footage shared online shows the moment gunfire rang out as people danced and celebrated. Screams can be heard as the crowd scattered in panic.
