Крамато́рськ tonight. This city is in Ukrainian-controlled Donetsk oblast.
Russia is recognizing this city and the rest of Ukrainian-controlled Donetsk and Luhansk oblasts as part of the separatist republics.
The banner says "Kramatorsk is Ukraine".
In April 2014 Russian-backed militants seized the city until the Ukrainian military retook the city in a long battle.
The ongoing war in the Donbas and the annexation of Crimea in 2014 already created over 1.6 million Internally Displaced People (IDP).
5 million from a larger invasion is if anything probably a conservative estimate. Ukraine is a country of over 40 million people.
I hope such scenarios don't come to pass. Even if you don't think the situation in Ukraine concerns you or don't think the US should get involved, please think of the human toll of this conflict.
