"Today, two hostages were released from militant captivity," Ukrainian President Petro Poroshenko tweeted on Sunday.
In turn, the adviser to the head of the Security Service of Ukraine, Yuriy Tandit said in an interview with 112 TV channel that mentioned Ukrainians were captured recently: "The operation has been prepared for several days; there were negotiations; and today we took back the two representatives of the State Emergency Service. They are in a safe place, taken in the direction of Kramatorsk. They are two of those those guys who were recently captured [by the militants]."
