Europe is continuing to swelter under a heatwave which has sent temperatures soaring right across the region.
Portugal is seeking help from Nato
At least 30 people have died in the blistering heat and in fires across the continent which are stretching emergency services to breaking point.
The death toll in Portugal rose to 14 after a couple were found dead in the aftermath of one blaze, as firefighters appeared to have brought most fires in the country under control.
But temperatures are continuing to reach 40C and with no sign of respite until next week at the earliest it is feared they could climb as high as 42C.
The Portuguese Government has asked Nato to provide water-carrying helicopters and equipment to help hundreds of firefighters still battling to control the blazes.
However, Nato spokesman Yves Brodeur told AFP news agency that there was little chance of the request being granted.
"There are few countries which possess such capabilities and those which have are using them," he said.
In neighbouring Spain, temperatures in the southern cities of Seville and Cordoba topped 41C. Three elderly women in the region died from the effects of the heat, bringing the country's total to 14.
