Israel says it's had "the most intense day" of fighting since its ground operation began in late October. The Israel Defense Force says its troops are in "the heart of Khan Younis" after bombarding the southern city overnight.

We'll hear from one of Israel's staunchest supporters in the US Congress.

The World Health Organisation says the situation in Gaza is getting worse by the hour, with bombardments by Israeli forces around Khan Younis and Rafah in southern Gaza. But the head of the Knesset Foreign Affairs and Defence Committee tell us that Israel is not trying to force everyone out of the Gaza Strip.

Also in the programme: the Nigerian president has called for an investigation into the deaths of at least 85 civilians after an army drone accidentally struck a village; and we speak to a scientist who is studying the world's biggest iceberg.

As Israel intensifies its offensive in southern Gaza, the US says it sees an improvement in the way which Israel is narrowing its targets. A resident of a southern Gazan city tells us it doesn't feel that way. We will also hear questions asked about the UN's response to the evidence of widespread sexual violence in the Hamas attacks.

And why, at the UN climate summit, a poet young is trying to make some noise.

As Israel mounts a ground offensive against Hamas in southern Gaza, a surgeon at a hospital in Khan Younis says it has more than 360 people on the operating list, which is "impossible to deal with", and supplies of anaesthetics and painkillers are running out.

Also in the programme: a Ugandan climate activist tells us that she is sceptical about change at the COP28 summit in Dubai; and voters in Venezuela have overwhelmingly approved its claim to territory in neighbouring Guyana, although the turnout in the referendum was low.

With the collapse of the temporary truce between Israel and Hamas, Southern Gaza has again become the focus of the Israeli military's offensive. As the language from the aid agencies still working in southern Gaza is becoming increasingly desperate, we hear from UNICEF spokesperson, James Elder.

Also in the programme: Venezuela is holding a controversial referendum, where the government wants voters to support its claim to a large part of neighbouring Guyana; and we hear from a Welsh man who kept a live bomb as a garden ornament.

Ministers from more than 60 countries are meeting at the UN climate conference in Dubai to discuss the health challenges posed by global warming. It is the first time the agenda of the annual event has dedicated an entire day to public health.

The Palestinian Red Crescent says the first humanitarian aid trucks have entered Gaza since a temporary ceasefire between Israel and Hamas collapsed on Friday. About fifty vehicles are reported to have been allowed through the Rafah crossing. Aid agencies say there's still a desperate shortage of supplies.

Also in the programme: We get the latest from the annual climate summit and ask to climate activists who have broken the law to support their cause; and we hear from the veteran feminist Gloria Steinem.

Fighting has resumed in Gaza after the seven-day temporary ceasefire between Israel and Hamas ended. We ask a member of Hamas politburo about the reasons for the end of the temporary ceasefire and about the remaining hostages.

The UN's Special Rapporteur for the Occupied Palestinian Territories, Francesca Albanese, has told the BBC the war in Gaza's resumption after a humanitarian pause is "a mistake". Ms Albanese has been an outspoken critic of Israeli treatment of Palestinians for years.

Both sides in the Israel-Hamas conflict have blamed each other for the resumption of hostilities in Gaza. Deadly fighting restarted immediately after the seven-day truce had expired. We'll hear from our correspondent in the south of Israel, where the resumption of explosions in Gaza is clearly visible and a senior advisor to the Israeli prime minister about why they have resumed hostilities.

Also in the programme: We'll hear the latest from Dubai where the second day of the UN's annual climate change conference is taking place and the head of the UN has a stark warning for the hosts, the UAE, one of the biggest oil producers in the world; and our royal correspondent tells us about anger at Buckingham Palace over the naming of two senior royals alleged to have made racist comments.
