The World Health Organization warned of a potential humanitarian catastrophe if an Israeli military offensive were to occur in Rafah, Gaza. The densely populated area, home to over a million Palestinians, is already facing a fragile health system. The offensive aims to target militants and free hostages, but details on evacuating civilians remain unclear. WHO's ability to distribute medical aid is hampered by denied requests for supply deliveries. The organization calls for humanitarian corridors to ensure aid can reach those in need.
