The Minsk-based trilateral contact group on a Donbas settlement has agreed on the so-called "school" ceasefire, effective as of 25 August, TASS has quoted Russian negotiator Boris Gryzlov as saying.
"We hope that the school ceasefire will be honoured responsibly and indefinitely," he said.
However, the issue of hostage release remains blocked due to the "non-constructive position" of the separatist republics, Darka Olifer, the spokesperson for Ukrainian negotiator Leonid Kuchma, has said on Facebook.
"Their representatives want 42 persons who have nothing to do with the developments in Donbas to be released," she said.
She added that Ukraine demands that the separatists stop their aggression and intimidation of OSCE observers.
