Firefighters Battle Large Wildfire Across U.S.-Mexico Border

SAN DIEGO, CA — Firefighters Sunday were battling a wildfire that expanded to 400 acres and crossed over the Mexican border from San Diego County.

The blaze erupted for unknown reasons around 12:35 p.m. Saturday near Buttewig Canyon in the South Slope of the Otay Mountain Wilderness and border area, according to an incident report from Cal Fire.

"The spread has reached 250 acres in the U.S., with 50% containment, and 150 acres in Mexico," Cal Fire PIO Brent Pascua told City News Service on Sunday.

Fire activity Saturday was low due to more humidity in the air from the marine layer. Firefighters will continue to work on increasing containment throughout the day, Cal Fire reported.

A total of 60 personnel are currently assigned to the fire, including five engines, two hand crews, two water tenders and three unnamed resources.
