Firefighters in Portugal are battling to contain wildfires engulfing thousands of hectares amid soaring temperatures.

Around 800 personnel attended a fire near the southern town of Odemira overnight on Monday, with more than 1,400 people having to evacuate.

At least nine firefighters have been injured tackling the fires.

Temperatures in excess of 40C (104F) are expected to hit much of the Iberian peninsula this week.

Three major fires that scorched hundreds of hectares in Spain over the weekend have been brought under control, but weather alerts remain in place across much of the country.

In Portugal, Monday saw a temperature of 46.4C (116F), the hottest of the year so far, recorded in Santarém.

The fire near Odemira began on Saturday and was driven south into the hilly interior of the Algarve, Portugal's main tourism region, by strong winds.

It has so far destroyed some 6,700 hectares (16,600 acres) of land, while a total of 19 villages, four tourist accommodations and a camping site have been evacuated.

The town's mayor, Helder Guerreiro, has said the situation is "critical, difficult, and complex".

In the centre of the country, other major fires prompted the closure of several stretches of motorway, including parts of the A1 between Lisbon and Porto.

Sixteen waterbombing aircraft have been deployed to support firefighting efforts across the two areas.

Authorities have declared more than 120 municipalities across Portugal at maximum risk of wildfires.

This week's heatwave will mark the third to hit the Iberian peninsula this summer.

Ruben del Campo of Spain's State Meteorological Agency told Reuters it was being caused by a large mass of hot, dry air from North Africa and would be "generally more intense, more widespread and a little longer-lasting" than the two that hit in July.

Climate change increases the risk of the hot, dry weather that is likely to fuel wildfires.

The world has already warmed by about 1.1C since the industrial era began and temperatures will keep rising unless governments around the world make steep cuts to emissions.
