Ukraine crisis: Russia stands firm despite rebukes, sanctions threats - CNN.com: "Moscow has defended its parliament's approval of Putin's use of military force to protect its citizens in the Crimean Peninsula, an autonomous region of eastern Ukraine with strong loyalty to Russia.
But Ukraine's ambassador to the U.N. says Russia's reasoning for a possible invasion is fake.
"There is no evidence that the Russian ethnic population or Russian-speaking population is under threat," Sergeyev told CNN.
The Russian parliament, or Duma, is also considering a law that would allow for the annexation of Crimea, according to the parliament's website.
"Now they are trying to create new legal basis to prove annexation of the territory they're now occupying," Sergeyev said.
