July 10 (UPI) -- A huge wildfire raging in southern Spain killed at least 11 people with another 19 unaccounted for, authorities said Friday as more than 700 firefighters and troops, nearly 200 firetrucks and 16 aircraft battled the flames.

The Andalusian government said in a post on X that all indications pointed to the main blaze, which had already burned through more than 3,000 acres near Los Gallardos in Almeria province, being sparked by a fallen power pole before spreading to woods nearby.

Warning casualty numbers could increase substantially, Andalusian President Juanma Moreno said eight people were injured, four of them seriously.

"I'm on my way to Almeria. The consequences of Los Gallardos are devastating. Right now, all efforts are focused on controlling the fire and preventing further loss of human life," he said in an update online.
