PARIS, July 3 (Reuters) – France, the Netherlands and Belgium have recorded 3,700 excess deaths during the June heatwave that sent temperatures soaring ​across Europe, with authorities warning that the ‌numbers are preliminary and could rise.

Experts have said the heatwave, which lasted from about June 20-28, was the worst recorded in Europe, causing disruption to power generation, damaging infrastructure ‌and ​overwhelming healthcare systems. The extreme heat ⁠was almost certainly ⁠driven by climate change, scientists said.

There were 2,025 excess deaths recorded in France during the heatwave, with a particular increase in deaths among people ​aged over 45, French Health Minister Stephanie Rist told local television on Friday.

Deaths at home rose ⁠91% between June 22-28 compared ⁠to the previous week, while deaths ​in nursing homes and healthcare facilities also increased, the ​country’s public health authority said in a bulletin.

“Mortality ‌will … be higher than these initial figures suggest,” the authority warned.

‘UNPRECEDENTED’ MORTALITY DATA

In Belgium, the Health Ministry said on Thursday it had registered excess mortality ⁠of about 1,200 deaths between June 18 and June 29, adding that 530 of the deaths were among people ⁠aged 85 ‌or older. People aged under 65 ⁠accounted for 180 of the excess deaths.

“Such ​excess ‌mortality during a heatwave is unprecedented ​in our ⁠country,” the ministry said in a statement.

Authorities in the Netherlands said the heatwave led to about 480 excess deaths, mainly among the over 80s.
