Israel appears to have shifted its focus to southern Gaza as it resumed aerial attacks on the Strip after a week-long pause in fighting and urged people to evacuate, prompting speculation that a new ground incursion could be imminent. The majority of Gaza’s population is now crowded in the south, and panic and confusion have gripped Palestinians in parts of Khan Younis. Under increasing public pressure from Western allies over the high civilian toll, Israel posted maps online that it said would help Palestinians make their way to a “safer” zone. Aid groups and displaced families have said the grids lack specifics and direct people to areas that are inaccessible, overcrowded or under attack. A U.S. warship in the Red Sea on Sunday shot down at least two drones, according to a U.S. defense official, with early assessments indicating that at least one was launched from a Houthi-controlled area of Yemen.
