Blood oozed through the soil at grave sites. You could see the pits move, some of them were still alive': The secrets of Ukraine's shameful 'Holocaust of Bullets' killing centre where 1.6million Jews were executed 

Seventy years on from the end of the Second World War the full, shocking scale of the Nazi-inspired Holocaust in Ukraine is finally being revealed - thanks to pioneering work by a French Catholic priest to research the truth of the industrial-scale killing.

Around 2,000 mass graves of Jewish victims have been located where men, women and children were shot and buried by the Germans and their collaborators

But there maybe up to 6,000 more sites to uncover, with victims of this 'Holocaust of bullets' - so called because unlike in Poland and Germany where gas chambers were used as the means of slaughter - here most were summarily shot and buried nearby

In many cases, the Jews were ordered to dig pits and then to strip n*ked before they were mown down by their murderers.

Some were buried in the unmarked plots while still alive.
