Sheriff’s deputies responded at 7:20 p.m. to an air emergency as crews were battling the Broadway fire near Cabazon, according to a post by the Riverside County Sheriff’s office on X, formerly known as Twitter.

The department is still investigating the crash and whether other aircraft were involved, Cordova said.

CBS News Los Angeles says a “fiery mid-air collision” occurred.

The station says the incident took place on Native American land, where firefighters were fighting a 20-acre fire, adding that it was unclear whether a burn area near the crash site was from the ongoing fire or from the impact of the collision.

Details weren’t immediately available on the number of injuries or fatalities.
