KYIV (Reuters) - Ukraine's foreign minister warned Russia on Thursday that an attack on his country would incur "political, economic and human losses" and would be too costly.

Russia has been building up forces near its border with Ukraine, and Kyiv, the United States and NATO have voiced concerns about a possible Russian attack -- a suggestion the Kremlin has dismissed as false.
