DONETSK, September 12. /ITAR-TASS/. The Ukrainian side has turned over six more prisoners of war to the self-defense forces in the east of Ukraine on Friday.

The prisoners were brought to the assigned place in the area of the settlement of Konstantinovka 60 kilometers south of Donetsk, ITAR-TASS reported from the scene. All of the servicemen returned from captivity were sent to a hospital for a medical examination. One of them has a bullet wound in his arm.

At 4.00 am Friday a total of 36 captivated soldiers of the Ukrainian army were exchanged into 31 representatives of the self-defense forces instead of the "37 to 37 swap" earlier planned.

Vice-premier of self-proclaimed Donetsk People's Republic (DNR) Andrei Purgun said that the two sides had exchanged the lists of prisoners of war once again Friday. The list of captivated DNR supporters numbers 500, while the Ukranian list has 95 names. Next, the prisoners of war will be swapped in two days' time, Purgin said.

All in all, official Kiev and the Donetsk and Luhansk People's Republic are planning to exchange up to 1,500 prisoners of war.

The tripartite Contact Group for settlement of the Ukrainian conflict, comprising Russia, Ukraine and the Organization for Security and Cooperation in Europe (OSCE), and representatives of the self-proclaimed Donetsk and Luhansk People’s Republics (DPR and LPR) agreed in Minsk on September 5 on a ceasefire in Ukraine’s embattled southeast.

The agreement came into force at 6:00 p.m. local time (15:00 GMT) on Friday, September 5.

The Contact Group met two days after Russian President Vladimir Putin suggested a seven-point plan to settle the crisis in Ukraine. Putin's peace plan envisages a ceasefire to be observed by all the armed formations in the southeast of Ukraine, withdrawal of armed formations to a safe distance from settlements, exercising international control over ceasefire, non-use of the Air Force against peaceful civilians, exchange of prisoners of war on the "all for all" basis, opening of humanitarian corridors and dispatching repair teams to the region to restore the ruined infrastructure.
