Sweltering temperatures hit much of Western Europe on Tuesday as a ferocious heatwave headed north.

The UK hit its highest ever temperature of 40.3C, according to provisional Met Office figures, and forecasters warned temperatures were still climbing.

Extreme heat warnings were issued in France and record July temperatures were reported in the Netherlands.

Deadly wildfires in France, Portugal, Spain and Greece have forced thousands of people to evacuate their homes.

Two people were killed by forest fires in Spain's north-western Zamora region and trains in the area were halted because of fire near the tracks. An elderly couple died while trying to escape fires in northern Portugal.

Heatwaves have become more frequent, more intense, and last longer because of human-induced climate change. German Environment Minister Steffi Lemke said the climate crisis meant the country had to rethink its preparations for very hot weather, drought and flooding.

Wildfires were still burning a day after several French cities including Nantes in the west saw their hottest-ever day.

More than 30,000 people have had to flee, with several camp sites destroyed and emergency shelters set up for evacuees.
