KIEV (Reuters) - Ukraine's military and separatist forces have agreed "in principle" on a new ceasefire from Dec. 5 in the rebel-held Luhansk region in the east of the country, the OSCE security group said.

The deal reported by the Organization for Security and Co-operation in Europe is the latest attempt to reinforce a much violated ceasefire agreed on Sept. 5.
