A health worker administers the Polio vaccine to a Palestinian child in Zawayda in the central Gaza Strip on September 1, 2024, amid the ongoing conflict between Israel and the militant group Hamas. The World Health Organization said Israel had agreed to at least three days of "humanitarian pauses" in parts of Gaza, starting on August 31, to facilitate a vaccination drive after the territory recorded its first case of polio in a quarter of a century.
