Ukraine expects to receive $11.8 billion in economic support this year from the United States, its prime minister said on Sunday.
Denys Shmyhal said during a televised conference in Kyiv that he was hopeful that US lawmakers would approve long-awaited economic and military aid.
Russia said on Sunday that its forces had taken more advantageous positions near Avdiivka and Donetsk after President Vladimir Putin ordered the military to push further into Ukraine after two years of full-scale war.
Russia's defense ministry said its troops had pushed back Ukrainian forces near Klishchiivka, Dyleyevka and Kurdiumivka in the Donetsk region and taken better positions near Avdiivka which fell to Russia earlier this month.
"In the Donetsk direction, units of the Southern grouping of troops improved the situation along the front line and defeated formations of the 22nd, 28th and 92nd mechanized brigades of the Armed Forces of Ukraine in the areas of the settlements of Klishchiivka, Dyleyevka and Kurdiumivka," it said.
"In the Avdiivka direction, units of the Center group of forces occupied more advantageous lines and positions, and also defeated manpower and equipment of the 3rd Assault Brigade of the Armed Forces of Ukraine and the 107th Air Defense Brigade."
The ministry said Russian troops had repelled seven Ukrainian counter-attacks in the area. A total of 77 Ukrainian drones were destroyed, the ministry said.
