US government wrote to Israel a month ago threatening sanctions if there was no increase in humanitarian supplies

• Middle East crisis – live updates

The amount of aid reaching Gaza has dropped to the lowest level since December, official Israeli figures show, despite the US having issued a 30-day ultimatum last month threatening sanctions if there was no increase in humanitarian supplies reaching the territory.

The ultimatum was delivered on 13 October, so will expire on Tuesday or Wednesday. It is unclear what measures Israel’s apparent failure to fulfil US demands will trigger, but they may include a temporary halt to the supply of some munitions or other military assistance.
