Putin says peace in east Ukraine is possible, but both sides not fully upholding a peace deal

Russia's president says he believes peace in Ukraine is possible but that neither side is fully holding up a peace deal struck in September.

In an interview with German television broadcast late Sunday, Putin said that he was convinced that it was possible to end the deadlock in east Ukraine, where pro-Russian rebels have been battling Kiev's troops in a conflict that has claimed at least 3,500 lives since March.

Putin also said that neither the rebels nor Ukrainian troops had fully withdrawn from key locations in the region to create a buffer zone, a key part of a truce deal agreed to in September.
