The Biden administration is stepping up criticism of Israel for not doing enough to improve humanitarian conditions in Gaza as a 30-day deadline looms for Israeli officials to meet certain requirements or risk potential restrictions on military assistance.

Israel says it's terminated the agreement facilitating the work of the U.N. agency for Palestinian refugees, the main provider of aid in Gaza.
