Firefighters were battling a vegetation fire that broke out in Marron Valley Sunday, but quickly brought it under control.

Units were dispatched around 11:30 a.m. to reports of a fire in a remote area of San Diego County, south of Dulzura and close to the Mexico border, said Cal Fire officials.

“The blaze was stopped at 12 acres. Fire personnel will remain at the scene for another two hours to mop up and patrol for hot spots,” Cal Fire PIO Captain Brent Pascua said.

No evacuations or injuries were reported, and the cause of the fire was not immediately known.
