Tens of thousands of Palestinians have returned to northern Gaza, celebrating despite the devastation. Authorities report 300,000 made the journey within 72 hours after Israeli forces opened the Netzarim corridor. The UN estimates most buildings across Gaza have been destroyed, with northern Gaza hit hardest. Many now shelter in ruined UN buildings with little access to food or water. Displacement since 2023 left families homeless the longest. Returning Palestinians reject any proposals to relocate them abroad, vowing to stay despite the harsh conditions.
