Humanitarian groups say almost none of the US’s demands that Israel improve conditions in Gaza have been met

A coalition of international aid organisations have accused Israel of ignoring a US ultimatum that threatened sanctions if Israel did not implement a series of measures to counter the acute humanitarian crisis in Gaza.

The 30-day ultimatum – which was due to expire yesterday or today – was delivered on 13 October, and almost none of its demands have been met, the humanitarian groups say.

Donald Trump has chosen the former Arkansas governor Mike Huckabee as the next US ambassador to Israel. Huckabee has a track record of hardline, occasionally provocative, pro-Israel rhetoric and previously said Israel has a rightful claim to the West Bank, which he refers to by its Hebrew and biblical name of Judea and Samaria.

Palestinian medical officials say Israeli airstrikes have killed at least 46 people in the Gaza Strip in the past 24 hours, including 11 at a makeshift cafeteria in an Israeli-declared humanitarian zone.

In Lebanon, warplanes struck Beirut’s southern suburbs and killed 33 people elsewhere across the country on Tuesday. Large explosions shook Beirut’s southern suburbs – an area known as Dahiyeh, where Hezbollah has a significant presence – soon after the Israeli military issued evacuation warnings for 11 houses there.

Lebanese state-run media reported an Israeli strike on an apartment south of the capital Beirut on Wednesday that injured an unspecified number of people. “Israeli warplanes launched a strike at dawn targeting a residential apartment in a building in the Dawhet Aramoun area, injuring people,” the official National News Agency said.

International Atomic Energy Agency chief Rafael Grossi will visit Tehran on Wednesday for crucial talks on Iran’s nuclear programme. His visit comes only two days after the Israel defence minister warned that Iran was “more exposed than ever to strikes on its nuclear facilities”.

US forces on Tuesday carried out strikes against targets linked to an Iranian-backed militia in Syria in response to a rocket attack on Washington’s troops in the country, the US military said. The strikes targeted the group’s “weapons storage and logistics headquarters facility … in response to a rocket attack on US personnel,” the US Central Command (Centcom) said in a post on social media that did not identify the militia by name.

Australia will not change its laws on the supply of weapons or ammunition to Israel if the coalition wins the next federal election, opposition foreign spokesperson Simon Birmingham says. The Liberal senator said the coalition had “no plans” to change the rules, as it emerged during a parliamentary hearing Australia had amended or lapsed at least 16 defence-related export permits to Israel after a review.
