More than 3,000 firemen struggled to put out forest fires across Portugal on Sunday, after the country requested assistance from Europe to fight blazes that threaten to spread with more hot weather in the coming days.
Exceptionally dry and hot weather ignited Portugal's worst fire disaster in memory early this summer, killing 64 people, and fires have continued to flare up in recent weeks with the arrival of each new hotter spell of weather.
Interior Minister Constanca Urbana de Sousa said the country sent the request for help to Europe late on Saturday because of concerns that high temperatures and high winds in the coming days could increase the number of fires.
The minister said the request was carried out "because of a question of prudence" due to the weather forecast for coming days, according to news agency Lusa. It covered requests for firefighting airplanes and firemen and is part of a European mechanism for cooperation to fight fires.
Emergency services said 268 fires broke out on Saturday, the highest number for any single day this year, with 6,500 firemen fighting to put them out. There are fears that many of them could flare up again later on Sunday, with higher winds and temperatures that hit in the afternoon.
The central district of Coimbra adopted a local state of emergency to deal with fires, as did four smaller municipalities in the region.
While fires have burned through the summer none has had the tragic impact of the one in late June, as emergency services have gone to far greater efforts to evacuate villages and shut roads early in affected areas.
But the country could face many more weeks of fires before the end of summer.
More than 140,000 hectares of forest have burned this summer in Portugal, more than three times higher than the average over the last 10 years, according to European Union data.
