At the headquarters of the Joint Centre for Control and Co-ordination (JCCC) in Debaltseve, the Ukrainian Major-General, head of the Ukrainian side, and the Russian Federation Army Chief of Staff indicated that in the 48 hours up to 08:00 hrs on 11 January there was a marked increase in reported ceasefire violations. During the period from 08.00 hrs on 9 January to 08.00 hrs on 10 January, a total of 72 ceasefire violations were noted (artillery and mortar shelling, small arms and light weapons fire and tank fire), of which 39 were recorded at the Donetsk airport. During the 24 hour period from 08.00 hrs on 10 January to 08.00 hrs on 11 January, a total of 111 ceasefire violations were recorded. Thirty-nine incidents were again recorded in the area of Donetsk airport.
On 10 January, the SMM monitored the security situation in Donetsk city and areas surrounding Donetsk airport. Between 16:57 hrs and 18:06 hrs, the SMM heard and directly observed multiple instances of both incoming and outgoing shelling (from unknown locations) consistent with heavy mortars, BM-21 multiple rocket launcher systems (Grad) and heavy artillery. While at a location near the airport, the SMM called the headquarters of the JCCC in government-controlled Debaltseve (55 km north-east of Donetsk) and asked the JCCC to try and halt ongoing hostilities in and around the airport. In response, the duty officer at the headquarters of the JCCC contacted the field commanders of both the Ukrainian armed forces and the "Donetsk People's Republic" (DPR) and asked them to stop the shelling. Despite the intervention of the JCCC, the SMM continued to observe numerous incoming and outgoing Grad rockets, mortars and artillery. No improvement in the situation was noted and the SMM left the area.
Besides, the residents in Kominternove (88 km south of Donetsk, located between government-controlled and "DPR"-controlled territories), told the SMM of their concern at having to obtain a pass to travel through government-controlled territory. Residents told the SMM that they do not know how to get these passes.
