Hamas-run Gaza’s health ministry said Monday Israeli forces were bombarding the last partially functioning hospital in the territory’s north, as Israel formally notified the UN it is cutting ties with the main aid agency for Palestinians. Vowing to stop Hamas from regrouping in northern Gaza, Israel launched a major air and ground assault nearly a month ago, a year into its war against the Islamists. Rescuers and UN agencies say hundreds of people have been killed and the area has been left desperately short of essential supplies.
