A new UN convoy was expected in Mariupol Friday to evacuate civilians from the "bleak hell" of a besieged steel plant that has become the last pocket of resistance against invading Russian forces in the southern port city.
The Russian military had announced a three-day ceasefire at the site starting Thursday but a Ukrainian commander said there was still heavy fighting at the sprawling Azovstal complex, where hundreds of soldiers and civilians have been holed up for weeks under heavy bombardment, AFP said.
Ten weeks into a war that has killed thousands, destroyed cities and uprooted more than 13 million people, Russia has focused its efforts on Ukraine's east and south, and taking full control of the now-flattened Mariupol would be a major victory for Moscow.
"A convoy is proceeding to get to Azovstal by tomorrow morning hopefully to receive those civilians remaining in that bleak hell," UN humanitarian chief Martin Griffiths told a Ukraine donor conference in Warsaw on Thursday.
The mayor of Mariupol estimates around 200 civilians remain sheltering in dismal conditions in the plant's Soviet-era underground tunnels.
"We still have to evacuate civilians from there, women and children. Just imagine... more than two months of constant bombing and constant death," Ukrainian President Volodymyr Zelensky said in his evening address on Thursday.
The International Committee of the Red Cross (ICRC) told AFP "that a safe passage operation is ongoing" in coordination with the UN. The two organizations have already worked together to evacuate some 100 civilians from the complex.
Speaking to the Israeli prime minister Thursday, Russian President Vladimir Putin said his military was ready to allow civilians to leave, according to the Kremlin.
"As for the militants remaining at Azovstal, the Kyiv authorities must give them an order to lay down their arms," Putin said.
A commander of the Azov regiment defending the factory said in a video on Telegram that there was still heavy bloody fighting.
"The Russians violated the promise of a truce and did not allow the evacuation of civilians who continue to hide from shelling in the basement of the plant," Svyatoslav Palamar said.
- Pentagon denial -
Since failing to take Kyiv early on in its invasion, which began February 24, Russia has focused its efforts on Ukraine's east and south.
Seizing the strategically located Mariupol would allow Moscow to create a land bridge between the separatist pro-Russian regions in eastern Ukraine and Crimea, which it annexed in 2014.
The Kremlin conceded Thursday that Kyiv's Western partners had prevented a quick end to Moscow's campaign by sharing intelligence and weapons with Ukraine, but that it was "incapable of hindering the achievement" of Russia's military operation.
The United States is among Ukraine's biggest backers, supplying military equipment and munitions worth billions of dollars as well as intelligence and training.
But the White House has sought to limit knowledge of the full extent of its assistance to avoid provoking Russia into a broader conflict beyond Ukraine.
Washington on Thursday denied an explosive report in The New York Times that it helped Ukraine target Russian generals.
"The United States provides battlefield intelligence to help the Ukrainians defend their country," National Security Council spokesperson Adrienne Watson said.
"We do not provide intelligence with the intent to kill Russian generals."
Separately, US media reported Thursday that Washington had shared intelligence that helped Ukraine sink the Russian warship Moskva last month.
However a US official, who spoke on condition of anonymity, told AFP that the United States does not "provide specific targeting information on ships."
- Fiji seizes oligarch's yacht -
Ukraine's government has estimated at least $600 billion will be needed to rebuild the country after the war.
President Zelensky, who has tirelessly campaigned for help from allies, on Thursday launched a global crowdfunding platform called United24 to help Ukraine win the war and rebuild its infrastructure.
More than six billion euros ($6.3 billion) were collected at a donors' conference in Warsaw, Polish Prime Minister Mateusz Morawiecki said Thursday.
In addition to financial and military assistance, Ukraine's allies have also punished Russia for the invasion with unprecedented sanctions.
In one of the latest such moves, the British government said Thursday it had frozen the assets of UK-based steel and mining firm Evraz as it is of strategic significance for Russia's war effort.
Evraz's main shareholder is Russian oligarch Roman Abramovich, who is already under sanctions, and its main operations are in Russia.
And in another action against oligarchs close to Putin, authorities in Fiji seized the $300 million yacht of Suleiman Kerimov after the United States requested be held for sanctions violations and ties to corruption.
- Farmers on the front line -
Fighting continued across eastern Ukraine.
Donbas regional governor Pavlo Kyrylenko said at least 25 civilians were wounded in an overnight Russian strike on the city of Kramatorsk.
Elsewhere, the Ukrainian army said it had retaken control of "several settlements on the border of Mykolaiv and Kherson regions".
In the southwest, farmers racing to keep up with the spring planting season have found themselves ploughing around unexploded ordnance -- one more piece of worrying news for next year's harvest in Europe's breadbasket.
"Every day since the start of the war we have been finding and destroying unexploded ammunition," Dmytro Polishchuk, one of the deminers, told AFP before heading into a field in the southwestern village of Grygorivka to destroy an unexploded rocket.
