KHAN YOUNIS, Gaza Strip (AP) — Palestinian authorities are calling for a cease-fire to evacuate three dozen newborns and other patients trapped inside Gaza’s biggest hospital as Israeli forces battled Hamas in the streets just outside and seized more ground across northern Gaza. The Israeli army has encircled Shifa Hospital, the facility it says Hamas hides in, and beneath, to use civilians as shields for its main command base. Hundreds of patients, medical staff and displaced people are trapped there with dwindling supplies and without electricity to run incubators and other equipment. Gaza’s largest hospital has emerged as a symbol of Palestinian suffering in the war between Israel and Hamas that extends far beyond its walls.
