Heat, drought and forest fires continue to affect large parts of southern Europe.
Portugal and neighboring Spain in particular suffer from peak temperatures of more than 40 degrees.
In Portugal, a pilot died when his fire-fighting plane crashed.
In the Italian Adriatic seaside resort of Bibione, tourists fled into the sea because of a forest fire and had to be rescued by the coast guard.

On the French Atlantic coast south of Bordeaux, after days of extinguishing work, there is hope that one of the two large forest fires will calm down.
The big forest fire on Crete, which was meanwhile considered controlled, flared up again on Saturday afternoon.
Strong winds fueled the flames near the village of Agios Vasilios, south of the port city of Rethymnon.
Another fire broke out near the port city of Heraklion on Saturday.
The intense heat on the Iberian Peninsula has already claimed more than a thousand lives.
The Carlos III Institute, which reports to the Spanish Ministry of Health.
recorded 360 deaths between July 10 and July 15, attributed to the extremely high temperatures.
The numbers increased day by day.
On Sunday a week ago there were 15 heat deaths, on Friday a new high was reached with 123 deaths.
Most of the deceased were older than 75 years or suffered from previous illnesses.
In neighboring Portugal, the Ministry of Health announced on Saturday evening that 659 people had died as a result of the heat wave with temperatures of up to 47 degrees in the past seven days.
The excess mortality peak was reached on Thursday, with 440 deaths in a single day.
Lisbon and the Tagus Valley are the most affected region.
Overall, however, the number of people who do not survive the recurring and intensifying major heat waves in south-west Europe continues to decline, mainly thanks to structural changes and air conditioning.
In 2003 there were almost 13,000 people in Spain.
According to the Spanish weather service Aemet, temperatures could drop slightly at the beginning of the week before rising again to up to 40 degrees.
As a result, the great fire hazard continues.
The worst of the more than 30 fires that have already burned more than 14,000 hectares of land raged in Extremadura, Andalusia, Castile and León and Galicia over the weekend.
Of most concern was the fire that broke out on Saturday night in the Garganta de los Infiernos area of the Jerte Valley, not far from Cáceres.
The regional government said it was laid "with full intention".
The fire at the edge of the Monfragüe National Park has not yet been extinguished.
In the Sierra de Mijas, above Málaga, evidence was mounting that a fire affecting an area of 1,900 hectares was caused by negligence or arson.
At times, more than 3,000 residents had to leave their homes and be taken to safety.
In Galicia in the northwest, the lightning from dry thunderstorms had apparently fueled numerous fires.
In Portugal, where temperatures dropped over the weekend, authorities reported two major wildfires in the north on Sunday.
In France, the Atlantic coast from Brittany to the Basque country is particularly affected by the heat wave.
The French weather service Meteo France has issued heat warnings for 37 departments.
Temperatures could exceed 40 degrees in several parts of the country this Monday.
The drought and heat favor the forest fires that have been raging near Bordeaux for a week.
More than 14,000 people, including holidaymakers from several campsites near the famous Pilat dune near Arcachon, had to be taken to emergency shelters.
The dune has been closed to visitors.
The thick clouds of smoke can be seen from the nearby beach of Pyla-sur-Mer.
The forest fires at La Teste-de-Buch and Landiras have already destroyed more than 10,000 hectares of forest.
Fire protection measures were stepped up on the Mediterranean coast.
The heat wave is also a challenge for French nuclear power plants.
The nuclear regulatory authority ASN has granted a special permit for the plants at Blayais near Bordeaux, Golfech in Occitania and Saint-Alban near Lyon.
Although the water temperature of the rivers exceeds the permitted maximum values, the plants are allowed to discharge used cooling water.
The electricity supply comes first, said ASN.
