Despite a week of tensions with Israel over its conduct of the Gaza War, Washington is reported to have authorised arms transfers to its ally worth billions of dollars.
These include more than 1,800 MK84 2,000lb (900kg) bombs and 500 MK82 500lb bombs, as well as 25 F35A fighter jets, The Washington Post and Reuters news agency have said.
The larger bombs have previously been linked to air strikes in Gaza causing mass casualties.
Washington gives $3.8bn (£3bn) in annual military assistance to Israel.
But the latest package comes as the Biden administration has been raising concerns about rising civilian deaths in Gaza and humanitarian access to the territory, which the UN says is on the verge of famine.
The administration has also said it “cannot support” an anticipated large-scale Israeli ground offensive in Rafah on the Egypt border, where there are more than a million displaced people.
The Palestinian ministry of foreign affairs in Ramallah criticised the US for inconsistencies in its positions.
The arms transfers have also been strongly criticised by some senior members of the president’s Democratic party who have been calling for US military aid to be limited or conditional on changes in how Israel conducts military operations.
