The Ukrainian president Volodomyr Zelensky visits the White House, six months after an Oval Office dressing down, and three days after Donald Trump rolled out the red carpet for Vladimir Putin. Several European leaders also flew to DC to show support for Ukraine. But is there any evidence of any progress towards peace? And on what terms?

Also in the programme: as Hamas says it accepts the latest Gaza ceasefire offer, our correspondent Lucy Williamson reports from the West Bank, where she witnessed Palestinian farmers being attacked by settlers; plus a cartographer explains why many maps literally distort our picture of the world - a problem the African Union has now joined calls to correct.

President Zelensky has condemned the latest deadly Russian attacks on Ukraine, ahead of his talks with President Trump and European leaders in Washington. Mr Zelensky accused Russia of carrying out what he called demonstrative killings to 'humiliate diplomatic efforts' to end the war. Ukraine says at least ten people have been killed in strikes on Kharkiv and Zaporizhzhia.

Also the Egyptian foreign minister and the Palestinian prime minister are visiting the Rafah border crossing with Gaza to highlight the need for more food aid to get through. We have an interview with the Palestinian prime minister, Mohammad Mustafa.

Can Donald Trump strike a deal with Vladimir Putin in Alaska today and get a ceasefire in Ukraine - and if so, on what terms? President Trump has previously spoken of 'land swaps' but Kyiv has already rejected the idea. We hear from a teenager who lived under Russian occupation in the Donbas for 10 years, and recently escaped.

Also in the programme: the world marks 80 years since Japan surrendered, ending World War Two; and as talks on a global plastics treaty collapse – again – is there any hope countries can ever agree?

There's been fierce international criticism of Israeli plans to build more than three-thousand homes in a controversial settlement in the occupied West Bank. The country's far-right finance minister, Bezalel Smotrich, said the move - which will split the territory - will "bury the idea of a Palestinian state". Britain's foreign secretary, David Lammy, described the plan as a "flagrant breach of international law" that "must be stopped".

Also in the programme: Humanitarian workers in Sudan say they lack the resources to deal with a deadly cholera outbreak in camps for people displaced by the civil war; what sort of welcome are Alaskans preparing for President Putin; and why are some female Australian birds developing male sex organs.

Ahead of the Trump / Putin meeting in Alaska, we ask what's happened to Ukraine's missing children? Ukraine says thousands have been taken by Russian forces - many indoctrinated in Russian military schools – and some are now fighting on the frontline against their home country.

Also in the programme: what are Israelis now thinking and saying about the war in Gaza – and how well informed are people about the conflict? Plus the good news that medication for ADHD may also reduce suicidal behaviours and substance misuse, and even make people less likely to have transport accidents and commit crime.

Amid the devastation in Gaza, remarkable stories of hope and resilience do emerge. Sixteen-year-old Sama Nijm, a gifted violinist from Gaza, is using music to bring comfort and healing to the youngest victims of the conflict. Some of the children have lost their parents, and in some cases, their limbs or arms.

BBC Newsday's Charlene Rodrigues spoke to Sama, and began by asking her what inspired her to become a violin teacher in the midst of war.

Russia has been trying to tackle a significant labour shortage by recruiting North Koreans; the BBC has been speaking to some of them.
