(FILES) Swedish climate activist Greta Thunberg (R) is seen on board of a vessel of a civilian flotilla, carrying pro-Palestinian activists, and humanitarian aid and aiming to break the Israeli blockade of the Gaza Strip, remains moored at Barcelona port on September 1, 2025, after being forced to return due to bad weather. Activists aboard a Gaza-bound aid flotilla said Israeli warships surrounded several of its boats on Wednesday and that the interception of the main vessels was under way. "The warships are moving in to intercept the flotilla -- only 81 nautical miles remain to Gaza," said the Maghreb contingent of the Global Sumud Flotilla in a statement. French politician Marie Mesmeur and Franco-Palestinian MEP Rima Hassan also reported that their boats were being intercepted. (Photo by Lluis GENE / AFP)
