Seventy-four hostages were returned to Ukraine. Sixteen of them were held captive in the so-called "Luhansk People's Republic" ("LPR"), while 58 Ukrainians were handed over by the so-called "Donetsk People's Republic" ("DPR").

Among those released from captivity of the "LPR" are Vladyslav Ovcharenko, Artyom Akmerov, Valentyn Bogdan and Eduard Nedelyayev. Among the Ukrainians released by the "DPR" are scientist Ihor Kozlovsky, public activist Volodymyr Fomichov and serviceman Oleksiy Kyrychenko, who was captured in 2014.

Ukraine extradited 73 people to the occupied Luhansk and 165 people to the occupied Donetsk.

Verkhovna Rada Commissioner for Human Rights Valeria Lutkovska reported that 43 from 306 people who had to be returned by the Ukrainian side had already served their sentences and had been released from custody before, so they did not come to the exchange.

There are also about 10-15 people who came for the swap, but refused to return to the areas controlled by the militants in Luhansk and Donetsk regions.
