Where it is inconvenient for them to go forward, they create real hell, shelling the territories on the horizon," he said.Kyrylenko warned the Russians were in the process of replenishing their troops in the region to prepare for further assaults. 'Terrorizing cities'Ukrainian President Volodymyr Zelensky said in his nightly address he had spent the day on the frontlines in the eastern Dnipropetrovsk region, where he met civilian and military leaders. "Officials must do not just everything possible, but much more than even possible, to guarantee people a normal standard of living even in such wartime conditions," he said. But in a Telegram message on Saturday, an official from the region's military administration warned Russia had "intentionally shelled residential areas," and had not stopped "terrorizing" the cities and villages.In the country's south, the mayor of Mykolaiv begged citizens not to leave shelters, as he said explosions were heard throughout the night. Ukraine's Deputy Prime Minister Iryna Vereshchuk was quoted by Ukrainian media as urging people in occupied areas to evacuate by any means possible. "Massive fighting is going to happen," she said. 'Further evolution of support'In a boost to Kyiv, Washington announced $400 million of further military aid, including a type of artillery ammunition with "greater precision" that has previously not been sent. "It's a further evolution in our support for Ukraine in this battle in the Donbas," a senior defense official was quoted by the U.S.

about the need for the aggression to end," Blinken said on Friday from the meeting on the resort island of Bali.Speaking outside the Mulia hotel, Lavrov remained defiant and accused Western nations of avoiding "talking about global economic issues" instead of the war.One official told AFP even Moscow's ally China had not offered "any full-throated endorsement" of the Russian position.Blinken shunned a bilateral meeting with Lavrov and instead accused Russia of triggering a global food crisis, demanding Moscow allow grain shipments out of war-battered Ukraine."To our Russian colleagues: Ukraine is not your country.

Its grain is not your grain.

Why are you blocking the ports? You should let the grain out," Blinken said in the closed-door talks, according to a Western official present.
