Spain on Friday warned of "very high or extreme fire danger in most of the country," as firefighters there continue battling 14 blazes in temperatures up to 104 degrees Fahrenheit.

The fires have spread over the regions of Extremadura, Galicia, and Castile and Leon, forcing authorities to suspend rail services and cut access to roads in the area, as well as blocking a 50-kilometre stretch of the popular Camino de Santiago pilgrimage trail.
