Biden, other G7 leaders, and Ukraine’s President Volodymyr Zelensky, are to meet virtually on Sunday to discuss Western support for Kyiv in its struggle against President Vladimir Putin’s invasion.
Zelensky said more than 40 women and children had been evacuated on Friday from the Mariupol steelworks after spending two months in underground shelters and that “diplomatic options” were underway to “rescue our soldiers.”
The Russian defense ministry gave a figure of 50 civilians evacuated, including 11 children, saying they were handed over to the UN and Red Cross, which are assisting in the operation.
It said the “humanitarian operation” would continue on Saturday.
About 200 civilians, including children, were estimated to still be trapped in the Soviet-era tunnels and bunkers beneath the sprawling Azovstal factory, along with a group of Ukrainian soldiers making their last stand.
Russia announced a daytime ceasefire at the plant for three days starting Thursday but the Ukrainian army said Russian “assault operations” had continued by ground and by air.
Ukraine’s Azov battalion, leading the defence at Azovstal, said one Ukrainian fighter had been killed and six wounded when Russian forces opened fire during an attempt to evacuate people by car.
Azov battalion leader Andriy Biletsky wrote on Telegram on Friday that the situation at the plant was critical.
“The shelling does not stop. Every minute of waiting is costing the lives of civilians, soldiers, and the wounded.”
May 9 fears
Ten weeks into a war that has killed thousands, destroyed cities and uprooted more than 13 million people, defeating the resistance at Azovstal and taking full control of strategically located Mariupol would be a major win for Moscow.
It would also be a symbolic success as 9 May approaches, the day Russia celebrates the Soviet victory over the Nazis in World War II.
Ukrainian officials believe Moscow is planning a 9 May military parade in Mariupol but the Kremlin denied any such plans.
White House Press Secretary Jen Psaki noted that the G7 meeting will come a day before “Victory Day” and the leaders will demonstrate “unity in our collective response” to “Putin’s war.”
“While (Putin) expected to be marching through the streets of Kyiv, that’s obviously not what’s going to happen,” Psaki said.
During previous evacuations from Mariupol, civilians left in white buses, some taking three days to complete a 230-kilometre (140-mile) journey to Ukraine-controlled Zaporizhzhia, passing through multiple Russian checkpoints.
In Zaporizhzhia, an elderly woman, Olga Babich, recounted to AFP on Friday the daily bombardments of her village in southeastern Ukraine.
A tearful Babich reached into her battered car’s backseat to retrieve kittens from a basket covered with a tea towel. “I couldn’t leave them. They want to live and they are so tiny,” she said.
Moscow-backed separatists in southeastern Ukraine meanwhile said they had removed Ukrainian and English language traffic signs for Mariupol, replacing them with Russian ones.
Locals want to see proof that “Russia has come back here forever,” said Denis Pushilin, head of Ukraine’s breakaway region of Donetsk.
Since failing to take Kyiv early on in the war, which began on 24 February, Russia has refocused its offensive on the south and east of Ukraine.
Taking full control of Mariupol would allow Moscow to create a land bridge between separatist, pro-Russian regions in the east and the Crimean peninsula, which it annexed in 2014.
Elsewhere, a Ukrainian official said Russian forces had almost encircled Severodonetsk, the easternmost city still held by Kyiv, and are trying to storm it.
Kherson in the south remains the only significant city Russia has managed to capture since the war began.
A senior official from the Russian parliament visiting Kherson on Friday said Russia would remain in southern Ukraine “forever.”
“There should be no doubt about this. There will be no return to the past,” Andrey Turchak said.
The Pentagon meanwhile denied reports it helped Ukrainian forces sink the Russian warship Moskva in the Black Sea last month.
Pentagon spokesman John Kirby said the US had “no prior knowledge” of the plan to strike the ship, which sank April 13, leaving a still-unclear number of Russian sailors dead or missing.
While providing Ukraine with military aid, the United States has sought to limit knowledge of the full extent of its assistance to avoid provoking Russia into a broader conflict beyond Ukraine.
Ukraine’s Western allies have supported Kyiv with financial and military assistance, and have slapped unprecedented sanctions on Russia.
In what would be its toughest move yet, the European Commission has proposed that all 27 EU members gradually ban Russian oil imports but Hungary rejects the ban.
The UN Security Council on Friday unanimously adopted its first declaration on Ukraine since Russia invaded on 24 February.
It backed Secretary General Antonio Guterres’s efforts to find a “peaceful solution” to the war but stopped short of supporting a mediation effort led by him.
Russia then vetoed a resolution condemning the invasion and asking Moscow to move its army back to Russian soil.
