Germany's Foreign Minister Frank-Walter Steinmeier said Ukraine crisis talks in a "Normandy format" in Berlin have ended with agreement representatives of Ukraine, Russia, and the OSCE would meet in the coming days to work out the details and timeline for pulling back heavy weapons in the east of the country.

Steinmeier said all sides agreed that pro-Russian fighters and Kyiv's forces should pull back heavy weaponry 15 kilometers from a demarcation line spelled out in a cease-fire deal agreed in Minsk in September.

Steinmeier said the agreement represented progress, but "no breakthrough" in efforts to achieve a peace accord for eastern Ukraine, where pro-Russian separatists have battled Ukrainian troops for nine months.
