Thousands of firefighters tackling deadly wildfires in central and northern Portugal had largely doused the flames in the Aveiro district, one of the worst-hit, as of Thursday morning, and were focusing on a dozen blazes still raging elsewhere.

Over 5,000 firefighters are battling more than 100 wildfires as EU countries provide additional planes to control the spread.

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