Fighting raged near Kyiv on Saturday and heavy shelling in other areas threatened new attempts to evacuate trapped civilians as France said Russian President Vladimir Putin showed no readiness to end the war in Ukraine.

Ukrainian President Volodymyr Zelenskiy said Moscow was sending in new troops after Ukrainian forces put 31 of Russia's battalion tactical groups out of action in what he called Russia's largest army losses in decades. It was not possible to verify his statements.

He also said about 1,300 Ukrainian troops had been killed so far and urged the West to get more involved in peace negotiations. The president suggested Russian forces would face a fight to the death if they sought to enter the capital.

"If they decide to carpet bomb (Kyiv), and simply erase the history of this region, the history of the Kyivan Rus, the history of Europe, and destroy all of us, then they will enter Kyiv. If that's their goal, let them come in, but they will have to live on this land by themselves," he told a news conference.

As per express news, Zelenskiy discussed the war with Chancellor Olaf Scholz and President Emmanuel Macron, and the German and French leaders then spoke to Putin by phone and urged the Russian leader to order an immediate ceasefire.

A Kremlin statement on the 75-minute call made no mention of a ceasefire and a French presidency official said: "We did not detect a willingness on Putin's part to end the war".

Russian Deputy Foreign Minister Sergei Ryabkov accused the United States of escalating tensions and said the situation had been complicated by convoys of Western arms shipments to Ukraine that Russian forces considered "legitimate targets".

In comments reported by the Tass news agency, Ryabkov made no specific threat, but any attack on such convoys before they reached Ukraine would risk widening the war.

Responding to Zelenskiy's call for the West to be more involved in peace negotiations, a U.S. State Department spokesperson said:

"If there are diplomatic steps that we can take that the Ukrainian government believes would be helpful, we're prepared to take them."

Crisis talks between Moscow and Kyiv have been continuing via a video link, Kremlin spokesperson Dmitry Peskov was quoted as saying by Russia's RIA news agency.

He gave no details but Ukrainian Foreign Minister Dmytro Kuleba said Kyiv would not surrender or accept any ultimatums. read more

HUMANITARIAN CORRIDORS

Air raid sirens blared across most Ukrainian cities on Saturday morning, local media reported.

Russian rocket attacks destroyed a Ukrainian airbase and hit an ammunition depot near the town of Vasylkiv in the Kyiv region, Interfax Ukraine quoted its mayor as saying.

The exhausted-looking governor of Chernihiv, around 150 km (100 miles) northeast of Kyiv, gave a video update in front of the ruins of the city's Ukraine Hotel, which he said had been hit.

"There is no such hotel anymore," Viacheslav Chaus said, wiping tears from his eyes. "But Ukraine itself still exists, and it will prevail."

Britain's defense ministry said fighting northwest of the capital continued, with the bulk of Russian ground forces 25 km (16 miles) from the center of Kyiv, which it has said Russia could attack within days.

Kharkiv, Chernihiv, Sumy, and Mariupol remained encircled under heavy Russian shelling, it said.
