MEXICO CITY, June 25 (Xinhua) -- At least 10 people, including children, were killed in a gunfight Tuesday night at a patron saint festival in Irapuato, a city in central Mexico's Guanajuato state, President Claudia Sheinbaum confirmed Wednesday morning.

"It was actually a clash but unfortunately children died," the president said at her daily press conference at the National Palace in Mexico City.

"What happened is very regrettable," Sheinbaum said, adding the investigation into the incident is underway and pledging to work with Guanajuato Governor Libia Dennise Garcia Munoz Ledo to address the ongoing violence in the state.

"We will continue to work together with the governor to the extent possible," the president said.
