The OSCE’s latest field report from Ukraine is dated last night at 19:30 hours, local time. According to the report, excerpted below, a significant amount of explosions were heard in Donetsk:

The SMM recorded ceasefire violations in several areas of Donetsk and Luhansk regions[1]. Positioned at “Donetsk People’s Republic” (“DPR”)-controlled Donetsk railway station (6km north-west of Donetsk city centre), the SMM heard a total of 87 explosions and multiple bursts of small-arms and light-weapons (SALW) fire, 3-8km to the north, north-north-west, north-west and west. While 81 explosions were undetermined, six of them were assessed as being consistent with the impact of 82mm-calibre mortar fire – weapons that are restricted at this distance to the contact line. Whilst in government-controlled Sopyne (16km east of Mariupol), the SMM also heard multiple bursts and several single shots of small-arms fire, as well as eight undetermined explosions 3-7km north and north-west of its position.

As the text above stresses, that the OSCE detected 82mm mortar fire is particularly concerning, indicating that heavy weapons are being used.

This is consistent with our reporting for the last two days.

In Lugansk, the OSCE’s observations are significantly less alarming. the report says, “All explosions and gunfire heard in Luhansk region were assessed as activities related to training or demining.”

But previous reports of shelling by both government and separatist sources appear to confirm that large-caliber weapons are once again shelling Donetsk region:

The SMM followed up on reports of shelling on both sides of the contact line. In government-controlled Pisky (11km north-west of Donetsk), the SMM saw four relatively fresh craters consistent with 120mm mortar rounds in a garden of the villa occupied by solders and assessed to have been fired from a south-easterly direction. A Ukrainian Armed Forces Commander told the SMM that shelling had occurred during the night of 6 December. In “LPR”-controlled Donetskyi (50km north-west of Luhansk), the SMM saw two relatively fresh craters 70m from a civilian house. The SMM assessed that they had been caused by 120mm calibre mortars fired from a northerly direction. Two armed individuals and one male resident told the SMM that the impacts had occurred during the night of 6 December.

Not all of the OSCE’s observations concern ceasefire violations as such. Some weapons observed by the OSCE were outside of respective ceasefire violations. But as the OSCE has noted in the past, much of this equipment could be repositioned toward the front lines in a matter of hours. Furthermore, the Russian-backed separatists have failed to provide the OSCE with an inventory of weapons and their storage sites, a requirement of the ceasefire agreements:

In areas of beyond the withdrawal lines – but outside storage sites – the SMM observed the following Addendum-related weapons: one tank (T-64) loaded on a flat-bed track heading south in “LPR”-controlled Luhansk city; two tanks at a training ground in “LPR”-controlled Uspenka (23km south-west of Luhansk); four tanks at a training ground in “LPR”-controlled Myrne (28km south-west of Luhansk); 31 tanks at a training ground in “LPR”-controlled Kruhlyk (31km south-west of Luhansk). The SMM continued to monitor the withdrawal of heavy weapons foreseen in the Minsk Package of measures. “DPR” members have yet to provide the requested inventory of heavy weapons and locations of designated permanent storage sites for these weapons, as requested by the SMM on 16 October. Members of the “LPR” had provided the SMM with an inventory of heavy weapons, their serial numbers and the locations at which they are said to be stored, as requested by the SMM. The Ukrainian military authorities had earlier provided an inventory list of military equipment featuring weapons systems as well as their serial numbers, but not the locations where the weapons are to be permanently withdrawn to.

The OSCE also monitored Ukrainian military positions:

The SMM revisited locations beyond the respective withdrawal lines known to the SMM as heavy weapons holding areas, even though they did not comply with the specific criteria set out in the 16 October notification. At such Ukrainian Armed Forces holding areas, the SMM observed: 11 multiple launch rocket systems (BM-21 Grad, 12mm), 14 self-propelled howitzers (2S3 Akatsiya, 152mm), and 12 anti-tank guns (D-48, 85mm). The SMM continued to observe Ukrainian Armed Forces presence in Pavlopil (26km north-east of Mariupol) (see SMM Daily Report 8 December), where it noted a number of military personnel and hardware. Staff of the village council and school teachers whom the SMM spoke to expressed their concern about the current situation, especially the presence of the Ukrainian Armed Forces and stated that since early December they had heard small-arms fire almost on a daily basis. During the night of 7 December they had heard six mortar rounds. The SMM observed that a number of residential houses in the village were occupied by the Ukrainian Armed Forces.
