From our newsroom:
Ukrainian Prime Minister Arseniy Yatsenyuk says Russia is still sending military forces into Ukraine despite a September 5 deal on a cease-fire and steps toward peace.
Yatsenyuk demanded Moscow remove what he called its "bandits" from Ukraine.
Speaking alongside German Chancellor Angela Merkel after their talks in Berlin, he said Russia has "sent troops to Ukraine's regions and continues sending its troops there."
"All this being done on the orders of Russian President Vladimir Putin," Yatsenyuk said.
Merkel said the agreement signed on September 5 in Minsk must be met in full for sanctions imposed on Russia to be lifted.
Russia denies involvement in the conflict in eastern Ukraine despite what Kyiv and NATO say is overwhelming evidence it has sent troops and weapons across the border to support pro-Russian separatists.
Yatsenyuk said that Russia "has not fulfilled a single point" of the Minsk agreement.
Latest on the potential EU loans:
The European Commission has offered to lend Ukraine a further 1.8 billion euros ($2.12 billion) in medium-term loans to help the country's beleaguered economy.
But the EU's executive arm said on January 8 that Ukraine must continue reforms under an International Monetary Fund (IMF) program and implement economic and financial policies agreed with the EU.
The bloc's 28 members and the European Parliament must approve the additional loans for them to go into effect.
The EU has already released 1.6 billion euros in loans to Ukraine to help bail out Kyiv's cash-strapped government.
Meanwhile, an IMF team on January 8 resumed talks with authorities in Kyiv about terms for a possible new loan to Ukraine.
An existing IMF bailout package is worth $17.1 billion, but only $4.6 billion has been paid out so far.
