"Last week" said the Pope, "the long awaited exchange of prisoners between the Russian Federation and Ukraine took place".
He told the faithful gathered that he rejoices "for the people who have regained their freedom, and are able to re-embrace their loved ones".
Pope Francis also said that he continues to pray "for a quick end to the conflict and for lasting peace in eastern Ukraine".
Last week, 33 Russians who were being held in Ukraine, landed in Moscow. On the same day, 35 Ukrainians, being held in Russia, landed in Kiev.
