A search operation is ongoing in Galway Bay for two missing swimmers after a 74-year-old man disappeared during a morning swim at Silverstrand beach. His absence was reported around 10:30 AM, while a woman in her 30s, who also went missing, prompted a search alert at 1 PM when she failed to arrive for work. Emergency services, including Gardaí, Coast Guard, and RNLI crews, are involved in the operation, which is challenged by heavy fog. Access to Silverstrand beach has been restricted as the search continues.
