The Guardian, working with media partners, has tracked down first-hand accounts to reconstruct Viktoriia Roshchyna’s final months

The exchange took place on a lonely forest road in February. Moving along a line of refrigerated lorries, the teams in hazmat suits went about their grim work: preparing the remains of 757 Ukrainian military casualties handed over by Russia for the journey back to Kyiv.

Clipboards in hand, intermediaries from the Red Cross checked their lists. For each body shrouded in white plastic, the Russians had provided a number, a name, a location, sometimes a cause of death. And then, at the very bottom of the last page, a mystery entry: “NM SPAS 757.” The letters were abbreviations, taken to mean “unidentified man” and “extensive damage to the coronary arteries”.

Kyiv responds to Russian announcement by calling for an immediate 30-day halt to fighting ‘not just for a parade’

Vladimir Putin has declared a three-day full ceasefire in the war with Ukraine in May to mark the 80th anniversary of the victory of the Soviet Union in the second world war.

The Kremlin said the 72-hour ceasefire would run from the start of 8 May to the end of 10 May, and called on Ukraine to join it as well. “All hostilities will be suspended during this period,” the Kremlin said in a statement. “Russia believes that the Ukrainian side should follow this example.”

Russian official calls talks with Steve Witkoff ‘quite useful’ as investigation launched into suspected Ukrainian bombing

Donald Trump’s envoy Steve Witkoff has met Vladimir Putin in the Kremlin for high-stakes peace talks, hours after a senior Russian military official was killed in a car explosion near Moscow.

Trump has played up Witkoff’s visit – his fourth to Russia in recent months – claiming a deal on ending the war in Ukraine was within reach. “The next few days are going to be very important. Meetings are taking place right now,” Trump told reporters on Thursday. “I think we’re going to make a deal … I think we’re getting very close.”

When his jet lands in Moscow, Steve Witkoff – Donald Trump’s envoy and longtime friend – will mark his fourth visit to Russia this year, a pointed gesture that says as much about who he is meeting as who he is not.

The 68-year-old real estate executive, who holds no formal diplomatic credentials, was expected in London on Wednesday for talks with Kyiv and European allies.

US president attacks Ukrainian counterpart for complaining Kyiv is unwilling to cede Crimea to Russia

Donald Trump has accused Volodymyr Zelenskyy of jeopardising what he claimed was an imminent peace deal to end the war in Ukraine, as he gave the clearest hint yet that the US would be willing to formally recognise Russia’s seizure of Crimea as part of any agreement.

The US president claimed a deal to end the war – largely negotiated between Washington and Moscow – was close, while the vice-president, JD Vance, said the agreement would include a proposal to freeze the conflict roughly along the current frontlines.
