Kiev, February 16 (RHC)-- A ceasefire is under threat in eastern Ukraine after taking effect this weekend. Sporadic fighting has reportedly broken out in several areas.
The Ukrainian military says separatists have continued attacks, while the rebels accuse Ukrainian forces of deploying heavy artillery. The pact calls for an end to attacks and the withdrawal of heavy weapons from the front lines.
Ukraine says it will not withdraw some heavy artillery, and shelling from both sides continues in the city of Debaltseve.
