Russian forces continued to bombard frontline Ukrainian cities on Sunday, hoping to gain military momentum as Kyiv launched a diplomatic counter-offensive against the world’s business and political elite gathered in Davos.

Shelling and missile strikes were launched against Kharkiv in the north, Mykolaiv, and Zaporizhzhia in the south, and eight civilians were killed on the eastern front in the Donbas, according to Ukrainian officials.

Three months after their invasion began, Moscow’s forces are focused on consolidating and expanding their gains in the Donbas region and along Ukraine’s southern coast.

Kyiv, meanwhile, is rallying international support and receiving Western weapons supplies, even if EU powers are struggling to agree on expanding sanctions on Russia’s huge energy exports.

Poland’s President Andrzej Duda was to address the Ukrainian parliament and meet President Volodymyr Zelensky later Sunday, a day ahead of the Ukrainian leader’s Davos videoconference.

“He will in particular pay homage to those who, in defending Ukraine, are fighting to defend Europe,” Duda’s adviser Jakub Kumoch told the news agency PAP.

The World Economic Forum brings together the world’s business and political elite in the Swiss mountain resort of Davos, and this year’s gathering will put Ukraine’s crisis at center stage.

Zelensky is due to hold a videoconference with delegates Monday evening to mark the opening of Ukraine House Davos, a forum for Kyiv and its international backers.

In March, Davos organizers cut ties with Russian firms and officials and announced that anyone under international sanctions would not be welcome at the event.

Western nations have rallied behind Ukraine’s defense of its territories, led by the United States — which just approved a $40-billion war chest for Kyiv — and neighbors like Poland.

But some European countries that are dependent on Russian oil supplies, such as Hungary, are resisting calls for an embargo on crude — and major EU economic powers like Germany remain huge gas importers.

The European Union is also reticent on Kyiv’s ambitions to join the bloc. France’s President Emmanuel Macron has suggested creating a “European political community” as a kind of antechamber to full membership.

Zelensky dismissed this idea.

“We don’t need such compromises,” he said Saturday during a joint news conference with visiting Portuguese Prime Minister Antonio Costa.

“Because, believe me, it will not be compromised with Ukraine in Europe, it will be another compromise between Europe and Russia.”

France’s Europe Minister insisted Sunday that “Ukraine is Europe”, without addressing a potential EU bid, adding that the immediate goal is “to avoid any Russian victory”.

But, while rejecting any concessions to Russia — and fighting to regain territory lost since Moscow began its offensive in late February — Kyiv knows that talks will come.

“There are things that can only be reached at the negotiating table,” Zelensky told Ukrainians Saturday.

The war, he said, “will be bloody, there will be fighting, but it will only definitively end through diplomacy”.

After just over 12 weeks of fierce fighting, Ukrainian forces have halted Russian attempts to seize Kyiv and the northern city of Kharkiv, but they are under intense pressure in the eastern Donbas region.

Moscow’s army has flattened and seized the Black Sea port of Mariupol and subjected Ukrainian troops and towns in the east to relentless ground and artillery attacks.

“There is no work, no food, no water,” said Angela Kopytsa, a 52-year-old with bleached hair, breaking into tears as she spoke to AFP reporters on a Russian-organised tour of Mariupol.

Kopytsa said both her home and life had been destroyed during the fighting in the port and that “children at maternity wards were dying of hunger”.

The once-bustling Azov Sea port city has lived without electricity since early March and has now been reduced to a wasteland, the carcasses of charred buildings stand amid the lush greenery of tree-lined streets and parks.

The incessant fighting of the previous weeks has died down, and the Russian army and its separatist allies now patrol the streets.

Elena Ilyina, who often teaches at a university in Mariupol, sobbed as she said  AFP about her life, saying her apartment has been completely destroyed and she is now living with her daughter.

“I have nothing left,” the 55-year-old said. “I’d like to live in my apartment, in peace, go to work and talk to my children.”
