Specialists wait for clients at the Opal salt treatment centre in Libya's eastern city of Benghazi on February 19, 2021. - The centre in Benghazi, where citizens rose up against dictator Moamer Kadhafi's rule a decade ago, opened Libya's first-ever artificial salt caves to clients last October. Established by two women entrepeneurs, the centre offers soothing treatments in a zen-like atmosphere accompanied by soft music and subdued lighting. "The inhalation of salt particles purifies the respiratory tract and brings benefits for the skin," says joint founder Iman Bugaighis, sporting a white blouse and a pink veil around her head.
