The World Health Organization said Sunday that over 1,300 excess deaths had been recorded in Europe since June 21 in connection with the record-breaking heatwave roasting much of the continent. And across Europe, "more than 1,300 excess deaths have been recorded since 21 June linked to high temperatures in Europe", WHO chief Tedros Adhanom Ghebreyesus said on X. "Heat stress is often called the 'silent killer' - and European homes, workplaces and schools were not built for these temperatures," he said.
