Terrain impeding wildfire fight in Calif.

SAN DIEGO, Nov. 8 (UPI) -- A fire official in San Diego said firefighting efforts against a wildfire in the California city's Del Cerro area is being impeded by terrain.

San Diego Fire-Rescue Department spokesman Maurice Luque said despite the use of 15 drops of fire-suppressing gel on the wildfire Saturday, the blaze still burned in the deep vegetation of a Del Cerro valley, the San Diego Union Tribune reported.

"It's difficult terrain," Luque said. "It's hard for crews to get in there."

Officials said Saturday night the blaze grew to nearly three acres north of Interstate 8.

Two helicopters and three brush rigs were helping nearly 45 firefighters attempt to control the wildfire Saturday, the Union-Tribune said.

Luque said the fire being investigated as having a suspicious origin, adding the canyon where the fire is burning is home to a homeless camp.
