As I suspected: May 2 at 4:30 am without declaring war junta gathered from the Nazis with the western districts of Ukraine and foreign mercenaries launched a punitive campaign against the civilian population. It all started under approving squeals by the U.S. government and the European Union. You can search a video statement about it on the Internet.
Actually started genocide to residents Sloviansk (the Second World War it was the same when attacked by German Nazis, then at the beginning of the town was 80,000, and survived only 10000).
This is particularly remarkable video: helicopter pilot who had attacked Slavic and was hit by militias, giving him medical care. Rather than shoot him.
Mercenaries with which he attacked, his threw - ie just landed next to another helicopter, examined him, took his gun and departed, leaving in the lurch.
P.S. Crimean militia sends aid to residents of Sloviansk and surrounded citizens by all of the Southeast, two battalions of soldiers.
This assistance will come in handy against those executioners who do not appreciate the lives of civilians.
