Ukrainian President Volodymyr Zelensky's Office says the agreements are being finalized on the lists and logistics of mutual release of held persons between Ukraine's Government and Russian-controlled forces in the self-proclaimed "Donetsk and Luhansk People's Republics" ("DPR"/"LPR") in Donbas.

"Another stage in the mutual release of held persons is indeed being prepared. Agreements are being finalized on the lists and logistics. The release is going to take place shortly. The date is constantly being updated," the Office reported via Telegram on April 15.

Also, the Office refuted reports posted by certain media that the swap had already begun. "Journalists have information that the return [of held Ukrainian citizens] is already underway. But this isn't true," the report said.

"Unfortunately, mutual release is a complex issue that requires additional coordination. In addition, this time the procedure is complicated by the fact that the release is taking place against the background of the [coronavirus] quarantine restrictions. Therefore, this requires setting up mandatory preliminary observation for our citizens, whom we are taking home," the Office added.
