WASHINGTON (Reuters) - Russian tanks and heavy military equipment have crossed the Ukrainian border in the last few days in breach of a European-brokered ceasefire agreed on Feb. 12, a senior U.S. State Department official said on Tuesday.
The comments by U.S. Assistant Secretary of State for Europe, Victoria Nuland, follow accusations by Ukraine and Western governments that Russia continues to send troops and weapons to support separatists in eastern Ukraine despite the Minsk ceasefire deal, a charge the Kremlin has denied.
