The China Mail - Ukraine orders end to defence of Mariupol

Russia's flattening of the strategic port city has drawn multiple accusations of war crimes, including a deadly attack on a maternity ward, and Ukraine has begun a reckoning for captured Russian troops.

The first post-invasion trial of a Russian soldier for war crimes neared its closely watched climax in Kyiv, after 21-year-old sergeant Vadim Shishimarin admitted to killing an unarmed civilian early in the offensive. The verdict is due on May 23.

Shishimarin told the court on Friday that he was "truly sorry" but his lawyer said in closing arguments that the young soldier was "not guilty" of premeditated murder and war crimes.

While Ukrainian forces fended off the Russian offensive around Kyiv, helped by a large infusion of Western arms, both eastern Ukraine and Mariupol in the south have borne the brunt of a ferocious ground and artillery attack.

President Volodymyr Zelensky's government received a fresh boost as the US Congress approved a $40-billion (38-billion-euro) aid package, including funds to enhance Ukraine's armoured vehicle fleet and air defence system.

And meeting in Germany, G7 industrialised nations pledged $19.8 billion to shore up Ukraine's shattered public finances.

Ukraine sorely needs enhanced capability to fend off the kind of onslaught Russia is waging in the eastern region of Donbas, a Russian-speaking area that has been partially controlled by pro-Kremlin separatists since 2014.

"In Donbas, the occupiers are trying to increase pressure," Zelensky said in his nightly video address late on Thursday. "There's hell -- and that's not an exaggeration."

In the eastern city of Severodonetsk, 12 people were killed and another 40 wounded by Russian shelling, the regional governor said.

- Burial with honours -

Zelensky described the bombardment of Severodonetsk as "brutal and absolutely pointless", as residents cowering in basements described an unending ordeal of terror.

The city forms part of the last pocket of Ukrainian resistance in Lugansk, which along with the neighbouring region of Donetsk comprises the Donbas war zone.

Russian Defence Minister Sergei Shoigu said his forces' campaign in Lugansk was "nearing completion".

Also apparently complete is the capture of the Azovstal steelworks, a totemic symbol of Ukraine's dogged resistance since Russian President Vladimir Putin launched the invasion on February 24 to remove a Western-leaning, "Nazi" threat on his borders.

Russia released a video appearing to show exhausted Ukrainian soldiers trudging out of the sprawling steel plant, after weeks during which the besieged defenders and civilians huddled in tunnels, enduring shortages of food, water and medicine.

"The higher military command has given the order to save the lives of the soldiers of our garrison and to stop defending the city," Azov battalion commander Denys Prokopenko said in a video on Telegram.

He said efforts continued to remove killed fighters from the plant.

"I now hope that soon, the families and all of Ukraine will be able to bury their fighters with honours," he said.

Ukraine is hoping to exchange the surrendering Azovstal soldiers for Russian prisoners. But in Donetsk, the pro-Kremlin authorities are in turn threatening to put some of them on trial.

"Our expectation is ... that all prisoners of war will be treated in accordance with the Geneva Convention and the law of war," Pentagon spokesman John Kirby said in Washington.

US President Joe Biden has cast the Ukraine war as part of a great US-led struggle of democracy against authoritarianism.

Biden offered "full, total, complete backing" to Finland and Sweden in their bid to join the NATO military alliance, when he gave their leaders a red-carpet welcome at the White House on Thursday.

- 'We're not idiots' -

But all 30 existing NATO members need to agree on any new entrants and Turkey has condemned the historically non-aligned Nordic neighbours' alleged toleration of Kurdish militants.

Shoigu said the Kremlin would respond to any NATO expansion by creating more military bases in western Russia.

As well as redrawing the security map of Europe, the conflict has sent shockwaves through the global economy, especially in energy and food markets.

Russia and Ukraine produce 30 percent of the world's wheat supply and the war has sent food prices surging. Russia is also a major exporter of fertiliser.

Washington urged Russia to allow exports of Ukrainian grain held up at Black Sea ports.

But former Russian president Dmitry Medvedev blamed the West.

"On the one hand, insane sanctions are being imposed against us. On the other hand, they are demanding food supplies," he said. "Things don't work like that. We're not idiots."
