Ukrainian President Volodymyr Zelensky has claimed the morale of Russian forces is crumbling.
In a Facebook message on Wednesday night, Zelensky said: "More and more occupiers are fleeing back to Russia, from us, from you, from all those who drive out the enemy with javelins, guns, tanks, helicopters - with everything that shoots. I wish you health, native Ukrainians, strong and kind, but not to the enemy!"
"We are a nation that broke the enemy's plans in a week — plans those have been built for years, vile, calculated, with hate for our country, for our people, for any people who have 2 things: freedom and heart. But we stopped them and beat them."
Zelensky added, "Our military, our border guards, our territorial defense, even ordinary farmers capture the Russian military every day. And all the captives say only one thing: they do not know why they are here. Despite the fact that there are dozens of times more of them, the morale of the enemy is constantly deteriorating."
He also mentioned the opposition to Russian forces of ordinary Ukrainians. "Blocking roads, people come out in front of enemy vehicles - it’s extremely dangerous, but how courageous. It is also salvation."
Zelensky accused Russian troops of looting.
"Let's throw them away with shame, as do those people who drive the occupiers out of grocery stores when the Russian military is trying to find food. These are not warriors of the superpower, these are confused children who were used. "
"They will not have peace here, they will not have food here, they will not have a single quiet moment here. The occupiers will receive only one thing from Ukraine — a rebuff, a worthy rebuff. They will always remember that we do not give up."
"Our army is doing everything to break the enemy completely. 9,000 Russians killed in one week," Zelensky said.
CNN cannot confirm Ukrainian estimates of how many casualties Russian forces have suffered.
