You haven't seen the recent OSCE reports I guess..
At the beginning of government-controlled Novodimytriivka village (51km north-west of Donetsk) the Ukrainian Armed Forces commander told the SMM that it could not continue to follow the convoy from government-controlled Selydove (43km north-west of Donetsk) and that he was not allowed to disclose its final destination.
South-west of government-controlled Bohoyavlenka village (48km south-west of Donetsk) the SMM was told by a commander of the Ukrainian Armed Forces that it could not continue to follow the convoy.
In government-controlled Klynove (64km north-east of Donetsk) the SMM could not continue to follow the convoy as a representative of the Ukrainian Armed Forces told the SMM that it was not allowed to do so.
At the entrance of Novoaidar (government-controlled, 57km north of Luhansk) the Ukrainian Armed Forces commander of a convoy of heavy weapons coming from government-controlled Raihorodka (34km north-east of Luhansk), told the SMM that it could not follow the convoy further.
A representative of the Ukrainian Armed Forces told the SMM that it was not allowed to monitor the further movement of self-propelled 152mm howitzer from government-controlled Stanytsia Luhanska (88km north-east of Luhansk) towards a northerly direction.
At a “DPR”-controlled checkpoint, north of Olenivka (22km south-west of Donetsk), the SMM was held up for 20 minutes until the local “DPR” commander came and escorted the SMM through Olenivka to the last “DPR”-controlled checkpoint south of the town.
At a Ukrainian Armed Forces checkpoint, 10 kilometres north of Mariupol, the SMM was held up for 35 minutes – and allowed to proceed only after contacting Ukrainian authorities.
On two separate occasions the checkpoint “commander” at a “DPR” checkpoint one kilometre east of Shyrokyne (20km east of Mariupol; 102km south of Donetsk) prevented the SMM from entering the village.
On two separate occasions, Ukrainian Armed Forces convoy commanders prevented the SMM from monitoring the movement of heavy weapons beyond government-controlled Shtormove (60km north-north-west of Luhansk).
-In three separate instances in the Donetsk region, Ukrainian Armed Forces convoy commanders prevented the SMM from monitoring the movement of military hardware beyond certain points.
