A deadly few days
French health minister Agnes Buzyn warned those tempted to plunge into cold water, both young and old, to do so only in designated public bathing areas, adding that four people had drowned since the beginning of the week.

Also Thursday, a six-year-old Syrian child was seriously injured after being catapulted into the air by water gushing from an open fire hydrant and then crashing to the ground.

They were hampered by roasting 44-degree temperatures and very low humidity according to David Borrell, head of the Catalan fire department.
Spain's northeast was on red heatwave alert denoting "extreme risk."
The stifling temperatures have caused air quality to nosedive in some European cities, prompting local authorities to take anti-pollution measures.
