WASHINGTON (AP) 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.

State Department spokesman Matthew Miller on Monday gave Israel a fail grade in terms of meeting the conditions for an improvement in aid deliveries to Gaza laid out in a letter last month to senior Israeli officials from Secretary of State Antony Blinken and Defense Secretary Lloyd Austin.

He said there were still roughly nine days until the deadline expires, but that limited progress so far has been insufficient.

As of today, the situation has not significantly turned around, Miller told reporters. We have seen an increase in some measurements. But if you look at the stipulated recommendations in the letter those have not been met.

A day before the U.S. election , the Biden administration called out its close ally, with support for Israel a key issue for many voters and the humanitarian crisis for Palestinians also a factor for many in the race. Former President Donald Trump and Vice President Kamala Harris have been competing for Muslim and Arab American voters and Jewish voters in battleground states like Michigan and Pennsylvania.
