The airstrikes occurred a day after the United States opposed a United Nations resolution calling for an immediate humanitarian cease-fire in Gaza, despite broad support.
In the 15-member Security Council, the vote was 13-1, with the United Kingdom abstaining.U.N.
Secretary-General Antonio Guterres described the attacks as intense and widespread, spanning air, land, and sea.
He informed the council that Gaza residents were navigating like human pinballs in ever-smaller areas in the south, lacking essentials for survival.
Guterres warned that Gaza was on the brink, with the humanitarian support system facing collapse, and he expressed concern about potential devastating consequences for the security of the entire region.
