Ukraine and Russia on Tuesday each released 90 soldiers back to their home countries in a further exchange of prisoners.
"Our people are home," Ukrainian President Volodymyr Zelensky said on Tuesday on social network platform X.
Zelensky said the soldiers were from different units of the armed forces, some of whom had fought in Mariupol before the city was captured by the Russians.
He said the returnees had fought against the Russian invasion in the Kherson, Donetsk, Zaporizhzhia, and Luhansk regions.
"We remember all our people in Russian captivity. We continue our work for the release of everyone," Zelensky said.
The defence ministry in Moscow announced that 90 Russian prisoners of war had been handed over by Ukraine. The men were transported to Moscow by military aircraft for treatment and rehabilitation in medical facilities.
Both sides released videos of the freed soldiers and thanked the United Arab Emirates for its role as a mediator.
The discussions about exchanging prisoners of war represent one of the few remaining channels of communication between Ukraine and Russia.
Russian President Vladimir Putin, who started the war more than two years ago, said at the beginning of June there were 1,348 Russian soldiers in Ukrainian captivity, while Russia has taken over 6,000 Ukrainian prisoners.
