The World Health Organization (WHO) warned of an “unfathomable catastrophe” if Israel launches a military offensive in Rafah, southern Gaza. Richard Peeperkorn, WHO representative, emphasized the densely populated area’s vulnerability. Over a million Palestinians, many displaced, reside in Rafah. Israel seeks to remove militants and free hostages without detailing civilian evacuation plans. WHO faces obstacles in distributing aid to Gaza due to denied requests, with only 40% of missions authorized since November, dropping significantly since January.
