The White House warned Russia to keep its troops out of Ukraine Sunday amid fears that Moscow may step in with military force following the overthrow of the president, its ally.
Tensions also mounted in Crimea, in the southeast of Ukraine, where pro-Russian politicians are organizing rallies and forming protest units, demanding autonomy from Kyiv.
The region is now seen as a potential flashpoint because of its deep strategic significance to Moscow.
U.S. President Barack Obama’s national security adviser said it would be a “grave mistake” for Russian President Vladimir Putin to send soldiers into Ukraine to restore a friendly government.
Susan Rice said nobody would benefit if Ukraine were to split apart.
