Firefighters battling the Mineral Fire west of Coalinga have increased containment, but the fire grew larger over the weekend, authorities said.

The eight-day-old Mineral Fire now covers more than 28,000 acres and was 49% contained as of 7:05 a.m. Monday morning.

Four structures have been destroyed, three structures have been damaged, and 60 are threatened. No injuries have been reported.

The challenge in containing the fire is gaining access to it in some areas.
