Saturday on PBS News Weekend, new airstrikes kill dozens across Gaza and the West Bank, as the Israeli military's search of Al Shifa Hospital forces hundreds to flee. As U.S. funding for Ukraine stalls, the war-torn country's humanitarian crisis gets worse. The growing need for nurse practitioners and the fight over how they provide care. Plus, the spread of mosquitos and the diseases they carry. PBS NewsHour is supported by - https://www.pbs.org/newshour/about/funders
