The World Health Organization said Wednesday that the closure of the Rafah border crossing meant health services in southern Gaza would run out of fuel in three days. “Without more aid flowing into Gaza, we cannot sustain our lifesaving support to hospitals,” WHO Director General Tedros Adhanom Ghebreyesus said at a briefing. President Biden told CNN Wednesday that he would halt the shipment of U.S. offensive weapons to Israel if the country moves ahead with a long-planned ground invasion of Rafah.
