Ukraine: 'Russia is invading'

The moment much of the world was hoping to avoid may be upon us. Russia has reportedly begun moving military forces into Ukraine, with NATO releasing satellite imagery showing Russian "Self-Propelled Artillery" convoys encroaching on Ukrainian soil. Ukraine is calling it an invasion.

This comes not long after Russian-supported resistance forces inside of Ukraine are believed to have shot down a commuter plane earlier this year. Tension between the two countries are nothing new, and Russia's annexation of Crimea earlier this year put an exclamation point on that.

Moving forces into Ukraine adds context to the ongoing squabble. Ukrainian President Petro Poroshenko met with Russian President Vladimir Putin Tuesday, though it wasn't clear at the time if any agreement or easing of bad-blood had been reached. Poroshenko said the meetings would decide "the fate or the World".

Two days ago Ukraine detained several Russian troops who they say crossed into the country without cause. Russia said those paratroopers did so by mistake, nothing more. This time, around 1,000 troops are believed to have crossed into Ukraine.

The situation is developing, and it's not known if Russia has engaged in any military action yet. Poroshenko canceled a previously scheduled appointment, where he was to attend the inauguration of new Turkish President Recep Tayyip Erdogan. Poroshenko said "Today the president's place is in Kiev", adding "I have decided to cancel my visit to Turkey because of the sharp escalation of the situation in the Donetsk region ... as Russian forces have entered Ukraine".
