A series of four initial deadly wildfires erupted across central Portugal in the afternoon of 17 June 2017 within minutes of each other, resulting in at least 66 deaths and 204 injured people.
The majority of deaths took place in the Pedrógão Grande municipality, when a fire swept across a road filled with evacuees escaping in their cars. Portuguese officials dispatched more than 1,700 firefighters nationwide to combat the blazes and Prime Minister António Costa declared three days of national mourning. Spain, France, Morocco and Italy deployed firefighters and water bombers to help extinguish the fires. Although most early official reports pointed to a dry thunderstorm as the cause of the tragedy, the President of the Portuguese Firefighters League expressed his conviction the fire was sparked by arsonists.
Four months later, the October 2017 Iberian wildfires would cause 45 deaths in Portugal and four in Spain, for a total of 115 deaths (111 in Portugal, 4 in Spain) between the two incidents.
