President Volodymyr Zelensky has visited the city of Kherson days after it was liberated by Ukrainian troops.
He spoke to soldiers, saying Ukraine is “moving forward” and ready for peace.
The loss of Kherson, taken in the early stages of the invasion, is a major setback for Russia – though Moscow insists it is still Russian territory.
Russia had declared it the administrative centre of the illegally-annexed Kherson region, and it was the only regional capital to be occupied.
Kherson was captured in March, in one of Russia’s major early successes in the war.
The region was then one of four to be illegally annexed after self-styled referendums were held in September.
Finally, Russian forces withdrew and Ukrainian troops entered the city on Friday.
Locals were seen celebrating, some reuniting with loved ones they had not seen for months. The mood in the city was one of jubilation and relief, but also trepidation and fear of what may come next, the BBC’s Jeremy Bowen reported.
In his visit on Monday, Mr Zelensky told troops that Ukraine is “ready for peace, peace for all our country,” the Reuters news agency reported.
He thanked Nato and other allies for their support in the war against Russia, adding that high mobility artillery rocket systems (Himars) from the United States had made a big difference for Kyiv.
The president addressed a crowd gathered in Kherson’s main square, some of whom waved Ukrainian flags or wore them draped across their shoulders, a Reuters journalist in Kherson said.
Mr Zelensky said he is “really happy” about the liberation, as are the people of Ukraine.
