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.

Five thousand firefighters struggled Tuesday to contain multiple wildfires raging across northern Portugal that are blamed for causing three deaths and forcing an unknown number of residents to flee their homes.

Portugal's firefighters have mastered most of the deadly forest fires in the north of the country, according to official data on Thursday.
