Ukraine at 'turning point', Zelensky says as Russians regroup near Kyiv

Ukraine was at a turning point in the war with Russian forces appearing to be regroup for a possible assault on Kyiv, President Volodymyr Zelensky said, as the United States imposed new sanctions on senior Kremlin officials and Russian oligarchs.

With the Russian assault in its third week, Zelensky, who has rallied his people with a series of addresses from the capital Kyiv, said Ukraine had "already reached a strategic turning point".

"It is impossible to say how many days we still have (ahead of us) to free Ukrainian land. But we can say we will do it," he said. "We are already moving towards our goal, our victory."

The United States on Friday imposed sanctions on Russian billionaire Viktor Vekselberg, three family members of President Vladimir Putin's spokesperson and lawmakers in the latest punishment for Russia's February 24 attacks.

"Treasury continues to hold Russian officials to account for enabling Putin's unjustified and unprovoked war," Treasury Secretary Janet Yellen said.

Russian forces kept up their bombardment of cities across the country on Friday in the biggest assault on a European country since World War Two. Satellite images showed them firing artillery as they advanced on Kyiv.

The fighting has created more than 2 million refugees, and thousands of Ukrainians are trapped in besieged cities.

As hundreds sheltered in Kharkiv metro stations, Nastya, a young girl lying on a makeshift bed on the floor of a train carriage, said she had been there for over a week, unable to move around much and ill with a virus.

"I'm scared for my home, for the homes of my friends, very scared for the whole country, and scared for myself of course," she said. read more

Putin calls the attacks a "special operation" to disarm Ukraine and unseat leaders it calls neo-Nazis. Ukraine and Western allies call this a baseless pretext for a war of choice that has raised fears of wider conflict in Europe.

Psychiatric hospital

The governor of the Kharkiv region on the Russian border, said a psychiatric hospital had been hit, and the mayor of the city of Kharkiv said about 50 schools there had been destroyed.

In the besieged southern city of Mariupol, the city council said at least 1,582 civilians had been killed by Russian shelling and a 12-day blockade that has left hundreds of thousands trapped with no food, water, heat or power.

Moscow denies targeting civilians.

Russia's defence ministry said the Black Sea port was surrounded, while Ukrainian officials accused Russia of deliberately preventing civilians getting out and humanitarian convoys getting in.

A new effort to evacuate civilians along a humanitarian corridor from Mariupol appeared to have failed, as Ukrainian Deputy Prime Minister Iryna Vereshchuk said Russian shelling prevented them from leaving.

"The situation is critical," Ukrainian interior ministry adviser Vadym Denysenko said.

Western countries meanwhile took more economic steps to try to force Putin to end his assault.

President Joe Biden, who this week banned U.S. imports of Russian oil, said the G7 industrial powers would revoke Russia's "most favoured nation" trade status.

Biden banned U.S. imports of Russian seafood, alcohol and diamonds. Washington sanctioned more oligarchs and elites, including board members of Russian banks, and a dozen lawmakers.

European Union leaders said they were ready to impose harsher sanctions on Russia and might give Ukraine more funds for arms. But they rejected Ukraine's request to join the bloc.

European Commission President Ursula von der Leyen said that the EU would on Saturday suspend Moscow's privileged trade and economic treatment, crack down on its use of crypto-assets, and ban the import of iron and steel goods from Russia, as well as the export of luxury goods in the other direction. read more

Gearing up

"You can't attack a country on a one-on-one ratio" of troops, Boulegue told Reuters. "Nobody has done it, which means that either something was wrong or they had very wrong assumptions."
