Paris authorities have activated emergency procedures as hospitals across the capital come under increasing pressure during a heatwave that has gripped France and much of Europe for more than a week. France 24's Antonia Kerrigan reports from the Hôpital Européen Georges-Pompidou, one of the largest hospitals in Paris, where the emergency department recorded around 3,000 admissions on Friday alone because of the extreme heat, a 36% increase compared with a normal day.
