Viktor Tereshchenko, mayor of the Velykoburlutska community in Ukraine's northeastern region of Kharkiv, has been released, according to a video message from Kharkiv Regional State Administration's head Oleh Syniehubov on Friday.
On Thursday, Syniehubov said Tereshchenko was "captured" by Russian forces.
"The enemy's released Viktor Tereshchenko. ... I've just spoken to him. He is at hospital receiving treatment. He is a good man who stands firm and sticks up for his community, his residents, his electorate. Once again this only proves that the enemy shall not prevail and no one will surrender an inch of our land to the enemy," Syniehubov said in the Friday statement.
He said that Russian forces did not allow the delivery of aid along the evacuation corridors, so local officials set up logistical aid centers in nearby towns that needed it most.
On Tuesday, the mayor of Melitopol, Ivan Fedorov, who had been detained by Russian forces, was freed as part of a prisoner swap. On Sunday Yevhen Matveyev, the leader of Dniprorudne, a small city north of Melitopol, was abducted by Russian troops, according to Ukraine's Foreign Minister Dmytro Kuleba.
CNN could not independently confirm the claim.
