Médecins Sans Frontières (MSF) teams are operating mobile clinics and restoring water and sanitation systems in Dahiyeh, south Beirut, where repeated Israeli airstrikes have destroyed health facilities, roads, and public infrastructure. Thousands of residents have been displaced multiple times since March 2026, and MSF warns that intensifying strikes across south Lebanon and the Bekaa Valley threaten to multiply humanitarian crises and erode health system capacity.
