NATO: 'High Probability' Russia Will Invade Ukraine

NATO said on Monday there was a "high probability" that Russia could launch an invasion of Ukraine, where the government said its troops have been closing in on Donetsk, the main city held by pro-Russian rebels.

Kiev said it was in the "final stages" of recapturing Donetsk, by far the biggest city under the control of the pro-Russian rebels. The battle for the city could be a decisive turning point in a conflict which has caused the biggest confrontation between Russia and the West since the Cold War.
