1 May 2017
While throughout Europe there are demonstrations dedicated to the International Day of Workers, in Ukraine, savage neo-Nazis attack those who dared to take to the streets.
In Vinnitsa, the radicals of the neo-Nazi organization “C14” attacked the May Day procession, trying to disperse it. The Nazis pulled out red flags with the inscriptions “Socialists” and “Union of Left Forces.” As a result, a fight broke out …
Similar attacks took place in Kharkov … where nationalists also beat people. Kherson was no exception: neo-Nazis from the “Right Sector” and “National Corps” (“Azov“) staged a fight with the inhabitants of Kherson.
Residents of the city from among the Union of Left Forces and the All-Ukrainian Union of Women “For the Future of the Children of Ukraine” tried to hold a May Day demonstration. But we came across opposition from the Ukrainian neo-Nazis.
From daily The Morning Star in Britain:
Monday 8th May 2017
Street fighters of the C14 group, a Transcarpathian Cossack outfit linked to the neonazi Right Sector party, attacked veterans on May Day with cries of “Ukraine is free” and “Commies to the gibbet,” according to witnesses.
The group’s name … is derived from the resemblance of the Cyrillic form of “sich,” a Cossack word for a command group, to C14 in Western script.
In the C14 name, the C also alludes to C18, the (originally English, later international) neonazi terror gang Combat 18. In which 18, the first and eighth letters in the alphabet, stands for ‘AH’=Adolf Hitler. The 14 in the C14 name stands for the ’14 words’, a racist neonazi slogan.
Ukraine’s government since the EU-backed coup of 2014 associates itself with the Organisation of Ukrainian Nationalists, which fought alongside the nazis in the second world war and helped carry out the Holocaust, and legislation removing May 9 — the anniversary of the nazi surrender to the Soviet Union — as a public holiday is going through parliament.
