The exchange was held on neutral territory by the formula of '222 for 150'.
The representatives of Ukraine have repeatedly stated earlier that there are more than 600 people held prisoners by the militants. The terrorists, in turn, recognized only 150 people.
The exchange of prisoners was previously scheduled for Saturday. The journalists were even invited to expand on this event.
By prior arrangement, the journalists must not be present at the exchange not to harm it. However, the Russian journalists were allowed to be present during the exchange, Hromadske reports quoting Defense Ministry Combined Coordination Center for Hostages' Exchange press-secretary Konstantin Zahorod'ko.
Hromadske notes that the announcement on the exchange results is expected to be made by President Poroshenko.
Security Service of Ukraine Chairman Advisor Markiian Lubkivskyi confirmed that the agency is afraid to disrupt the process, so the Ukrainian journalists are not allowed to the exchange site.
"We may speak about certain figures only when the procedure is complete. I'm asking everybody to understand that the procedure takes place under very difficult conditions," he said on air of Hromadske, explaining why so few details were reported.
Russia Today TV channel propagandist Roman Kosarev posted pictures of the exchange on his Twitter account.
