A large section of cliff near the Miramar lighthouse in Biarritz collapses into the Bay of Biscay, burying three divers and killing one woman after about 2,000 square meters of rock fall.Rescue teams suspend searches overnight and cordon off roughly 300 meters of coast, prohibiting swimming and boating while geotechnical experts assess cliff stability and the risk of further rockfalls.Officials note previous collapses at the site in 2008 and 2018 and say investigators are examining whether the current heatwave and long-term coastal erosion contributed to the failure.
