KIEV, (Sputnik) – Artillery fire was heard in the eastern Ukrainian city of Luhansk after the ceasefire was enforced, the chief of Organization for Security and Co-operation in Europe (OSCE) Special Monitoring Mission in Ukraine said Sunday.
"In the Luhansk region, outgoing artillery rounds being fired were heard in Luhansk city at 01:45 [23:45 GMT]," Ertugrul Apakan said during a press briefing in Kiev.
The ceasefire took effect on Sunday at midnight Ukrainian time (February 14, 22:00 GMT).
According to Apakan, artillery fire was also heard in an area 21km [13 miles] from Luhansk.
The truce agreement was a part of the deal between Ukraine and independence militias, brokered by the leaders of Russia, France and Germany on Thursday.
The agreement stipulates that the OSCE must conduct a thorough monitoring of the ceasefire. The organization's Special Monitoring Mission has been reporting on the situation in Ukraine since March 2014.
