The U.N. High Commissioner for Human Rights said most civilian casualties were caused by the use of “explosive weapons with a wide impact area, including shelling from heavy artillery and multi-launch rocket systems, and missile and air strikes.”

Moscow has repeatedly denied attacking civilian areas.

In Irpin, a town some 25 km (16 miles) northwest of the capital Kyiv, men, women and children trying to escape heavy fighting in the area were forced to take cover when missiles struck nearby, according to Reuters witnesses.

Soldiers and fellow residents helped the elderly hurry to a bus filled with frightened people, some cowering as they waited to be driven to safety.

The invasion has drawn almost universal condemnation around the world, sent more than 1.5 million Ukrainians fleeing from the country, and triggered sweeping Western sanctions against Russia aimed at crippling its economy. The Biden administration said on Sunday it was exploring banning Russian oil imports.

“War is madness, please stop,” Pope Francis said in his weekly address to crowds in St Peter’s Square, adding that “rivers of blood and tears” were flowing in Ukraine’s war.

Putin made his demand for Kyiv to end the fighting in a phone call with Turkish President Tayyip Erdogan, who appealed for a ceasefire. Putin told Erdogan he was ready for dialogue with Ukraine and foreign partners but any attempt to draw out negotiation would fail, a Kremlin statement said.

Russian media said Putin also spoke by phone for almost two hours with French President Emmanuel Macron. Macron told Putin he was concerned about a possible imminent attack on southern Ukraine’s historic port city of Odessa, Macron’s office said.

Anti-war protests took place around the world including in Russia itself, where police detained more than 4,300 people, an independent protest monitoring group said. The interior ministry said 3,500 demonstrators had been held, included 1,700 people in Moscow and 750 in St Petersburg.

Reuters was unable to independently verify the footage and photographs.

Demonstrations were also taking place in Western capitals as well as in India and Kazakhstan, after jailed Kremlin critic Alexei Navalny called for worldwide protests against the war.

In the besieged city of Mariupol, authorities had said on Sunday they would make a second attempt to evacuate some of the 400,000 residents. But the ceasefire plan collapsed, as it had on Saturday, with each side blaming the other.

A huge Russian convoy north of Kyiv appears to have made limited progress in recent days, although Russia’s defence ministry released footage on Sunday showing some tracked military vehicles on the move.

In the capital, Ukrainian soldiers bolstered defences by digging trenches, blocking roads and liaising with civil defence units as Russian forces bombarded areas nearby.

Ukrainian President Volodymyr Zelenskiy said Russian rockets had destroyed the civilian airport of the central-western region capital of Vinnytsia on Sunday.

Kyiv renewed its appeal to the West to toughen sanctions, and also requested more weapons, including a plea for Russian-made planes, to help it repel Russian forces.

Speaking on a trip to neighbouring Moldova, Blinken said Washington was considering how it could backfill aircraft for Poland, if Warsaw decided to supply its warplanes to Ukraine.

Putin says he wants a “demilitarised”, “denazified” and neutral Ukraine, and on Saturday likened Western sanctions “to a declaration of war”.

But Washington and its NATO allies have resisted Ukraine’s plea for a no-fly zone, saying it would escalate the conflict beyond Ukraine’s borders.

Ukrainians continued to pour into Poland, Romania, Slovakia and elsewhere. The United Nations said over 1.5 million had fled in Europe’s fastest growing refugee crisis since World War Two.

Western sanctions have pushed many companies to exit investments in Russia, while some Russian banks have been shut out of a global financial payment systems, driving down the rouble and forcing Moscow to jack up interest rates.

On Sunday, American Express Co said it was suspending all operations in Russia and Belarus. Video sharing app TikTok said it was suspending livestreaming and the uploading of new content to its service in Russia.

Speaking on NBC’s “Meet the Press” show, Blinken said the United States and European partners are exploring banning Russian oil imports, but stressed the importance of steady oil supplies globally.

The West has so far refrained from direct measures on Russian energy exports after oil soared to multi-year highs.

Ukraine’s military said more than 11,000 Russian troops had been killed so far and 88 Russian aircraft shot down since the start of the invasion. Reuters could not corroborate the claim. Russia has not given regular updates on its death toll.

Tass news agency cited Russian defence ministry spokesman Igor Konashenkov as saying virtually the entire Ukrainian air force had been destroyed. In the last 36 hours alone, he said, Ukraine had lost 11 combat aircraft and two helicopters. Reuters had no way of corroborating the claim.
