Israeli offensive in hard-hit northern Gaza kills and wounds dozens and threatens hospitals

Palestinians say a large-scale Israeli operation in northern Gaza has killed and wounded dozens of people and threatens to shut down three hospitals. Heavy fighting was underway Wednesday in Jabaliya, where Israeli forces have carried out several major operations over the course of the war, only to return as militants regroup. The entire north, including Gaza City, has suffered heavy destruction and has been largely isolated by Israeli forces since late last year. The continuing cycle of death and destruction in Gaza offers a cautionary tale as Israel expands a week-old ground offensive against Hezbollah in Lebanon and considers a retaliatory strike on Iran after its missile attack last week.
