The West 'has ignored' Russia's key security concerns, says Vladimir Putin

Russian President Vladimir Putin said his government was studying the responses from the United States and NATO to Russia's security concerns, but said his country's main complaints "had been ignored."

For weeks Putin had remained tight-lipped about a possible invasion of Ukraine, making scant public remarks about the crisis and the buildup of tens of thousands of Russian troops near the Ukrainian border.

But speaking at a Tuesday news conference following a five-hour meeting in Moscow with Hungarian Prime Minister Viktor Orban, the Russian President said: "It is already clear -- I informed the Prime Minister about this -- that the fundamental Russian concerns were ignored. We did not see an adequate consideration of our three key requirements."
