Ukraine : The UN Security Council has warned of a “dangerous deterioration” in eastern Ukraine and called on warring sides to halt the violence.
The council said renewed fighting was having a “severe impact” on civilians.
Fighting in the frontline town of Avdiivka has left thousands of residents without water or power in freezing conditions.
Ukraine says it is preparing a possible evacuation of the town to avoid a humanitarian crisis.
Each side blames the other for the upsurge in violence.
“The members of the Security Council called for an immediate return to a ceasefire regime,” the Ukrainian-drafted statement said.
