PARIS (AP) — Barcelona recorded its hottest June in over a century, the summit of Paris’ iconic Eiffel Tower was closed to visitors and hundreds of French schools shut on Tuesday as Europe sizzled in its first major heat wave of the summer.

The Eiffel Tower closed early on Tuesday and will remain closed on Wednesday as a sweltering heat wave grips parts of Europe.

A marine heat wave in the Mediterranean is combining with a powerful heat dome to cause Europe to swelter under a brutal early summer heat wave.
