‘In denial’

In Catalonia, firefighters battled a blaze in Torre de l’Espanyol, a municipality in the Catalan province of Tarragona. The fire – the worst in the region in 20 years – is believed to have been caused when farm manure spontaneously combusted. Authorities have warned that the fire has the potential to consume an area of 20,000 hectares or 28,000 soccer pitches
“The terrain is complicated, this generates a lot of difficulties, the weather conditions are not favourable,” David Borrell, head of the Catalan fire department, told local radio. After 350 firemen worked all Wednesday night to contain the blaze, joined by two hydroplanes on Thursday morning, he said it was “hard to be optimistic”.
