In addition, the mission also recorded the presence of people in the evening and at night within two areas of the disengagement of forces - Zolote and Petrovske.
In particular, in Donetsk and Luhansk regions, 92 explosions, two ammunition, six flares and 534 rounds and shots were recorded.
On August 20, 153 ceasefire violations were recorded in Donbas, of which three explosions. At the same time, the headquarters of the Joint Forces Operation reported that the militants opened fire twice on 20 August.
"The data differ because the OSCE considers every shot or explosion as a violation, and the Joint Forces Operation (JFO) headquarter considers shelling of one position as one fact of violation," the Mission added.
According to the JFO headquarters, over the past day, on August 21, there were no shelling and other violations by illegal armed groups of the agreements reached on a ceasefire in Donbas.
