The State Department said on Tuesday that it did not plan to decrease weapons aid to Israel, as a 30-day deadline set by the Biden administration passed without the country substantially improving the humanitarian situation in war-devastated Gaza.

Secretary of State Antony J. Blinken and Defense Secretary Lloyd J. Austin III had warned in a letter dated Oct. 13 that the United States would reassess its military aid to Israel if it failed to increase the amount of aid allowed to enter Gaza within 30 days.

The letter said that the humanitarian situation for the two million residents of Gaza was “increasingly dire” and that the amount of aid entering Gaza had fallen by 50 percent since April.

By law, the U.S. government cannot give aid to foreign military forces deemed by the State Department to be committing “gross violations of human rights.”

U.N. officials have said Israel’s continued blocking of humanitarian aid and targeting of humanitarian workers constitute violations of international law and could amount to war crimes.

Food insecurity experts working on an initiative controlled by U.N. bodies and major relief agencies said last week that famine was imminent or most likely already occurring in northern Gaza. U.N. officials say the entire population of Gaza is facing food insecurity.
