Ukraine(CNN)Russian President Vladimir Putin has ordered troops into separatist-held parts of eastern Ukraine in what the Kremlin called a "peacekeeping" mission, just hours after he signed decrees recognizing the independence of the Moscow-backed regions. It is unclear if Russian troop movements marked the beginning of an invasion of Ukraine that Western leaders have warned about for weeks. But multiple US and Western officials cautioned Monday's move could serve as the opening salvo of a larger military operation targeting the country. US Ambassador to the UN Linda Thomas-Greenfield told an emergency meeting of the UN Security Council Monday evening that Putin's recognition of the pro-Moscow regions was an "attempt to create a pretext for a further invasion."
