Secretary of State John Kerry says the Russian buildup of troops on its border with Ukraine is creating a climate of fear and intimidation in that country.

Kerry spoke after meeting Sunday night in Paris with Russian Foreign Minister Sergey Lavrov and said he told the diplomat that Ukrainians must be allowed to decide their own future.

"The United States is consulting with Ukraine at every step of this process, and we will not accept the path forward if the legitimate government of Ukraine is not at the table,'' Kerry said.

Kerry described his talks with the Russian diplomat as "a frank conversation" about Russia's moves in Crimea and the large gathering of troops along the border with Ukraine.

"I made clear the United States still considers the Russian actions to be illegal and illegitimate,'' Kerry said.

Kerry was heard to say, "I'm warning you, don't make me get up and come over there!"
