Nearly a month after wildfires blazed on the Portuguese island of Madeira, more fires have broken out in mainland Portugal . Seven people have reportedly died so far in the fires, which are spreading between the northern district of Aveiro and Porto .

Fire services in the town of Arouca, near Porto, described the situation as “uncontrollable” as they fought three separate blazes. Margarida Belém, president of the local chamber, said that 15 villages in the area were isolated because of the fires.

Firefighters tackling deadly wildfires in central and northern Portugal had doused the flames in the Aveiro district, one of the worst-hit, as of Thursday, and were focusing on eight large blazes still raging elsewhere.
