(COLOS, Portugal) — More than 1,000 firefighters on Monday were battling a major wildfire amid scorching temperatures in Portugal, where forest blazes wreak destruction every summer. About 90% of the fire area in the Castelo Branco district, 200 kilometers (about 125 miles) northeast of the capital Lisbon, was brought under control during cooler overnight temperatures, according to local Civil Protection Agency commander Pedro Nunes. But authorities said they expected heat in and winds to increase again in the afternoon, so all firefighting assets remained in place.
