Israeli Prime Minister Benjamin Netanyahu's criticism this week over US weapons deliveries to his country is "vexing," the White House said on Thursday.

"Those comments were deeply disappointing and certainly vexing to us, given the amount of support that we have and will continue to provide," National Security Council spokesman John Kirby told journalists.

In a video statement, Netanyahu said that while he appreciated America's support during the Gaza war, "it's inconceivable that in the past few months, the administration has been withholding weapons and ammunitions to Israel."

The United States however has said that there is only one shipment of 2,000 pound bombs that is under review because of concerns about their use in densely populated areas.

Kirby separately said that US National Security Advisor Jake Sullivan is due to meet his Israeli counterpart Tzachi Hanegbi and Strategic Affairs Minister Ron Dermer on Thursday.

Washington is Israel's main military backer, but the White House has voiced frustration over the rising civilian death toll in Gaza, where Israel has conducted more than eight months of operations against Hamas.

The war was triggered by an unprecedented October 7 attack by Palestinian militants on southern Israel, which resulted in the deaths of 1,194 people, mostly civilians, according to an AFP tally based on Israeli official figures.

Israel's retaliatory offensive in Gaza has killed at least 37,431 people, also mostly civilians, according to the health ministry in the Hamas-ruled territory.
