PARIS (AP) — Europe is baking under unseasonal heat that is shattering temperature records, including in the United Kingdom on Monday, and prompting government warnings after deaths were reported at amateur sports events in France.

The French sports minister, Marina Ferrari, posted condolences to the loved ones of a runner who died Sunday in a Paris race. Le Parisien newspaper reported that the 53-year-old man suffered a heart attack during the run in the capital’s 20th arrondissement, and that firefighters were unable to revive him.

It wasn’t yet known if the cause of the runner’s death was heat-related, but Ferrari suggested a possible link. Temperatures in Paris went as high as 32 C ( 90 F) in the afternoon.
