In a statement, the U.N. World Health Organization said Gaza’s hospitals and health facilities “are in dire need of support” from international donors. The WHO says 15 of Gaza’s 32 hospitals have been damaged, in addition to 18 primary health clinics and 29 ambulances. A health official with the U.N. agency for Palestinian refugees said: “While we do our best, we are deeply concerned about the health and hygiene situation in our very crowded shelters. Our efforts may be limited where the entire water, electricity and sewage systems are heavily damaged.”
