Memories of the early spring three decades ago remind us of cries of thousands of Albanian students. Serbs had poisoned innocent young people in many schools in Kosovo. But the Yugoslav state never admitted this. Doctors and professors told KosovaPress, about what happened in March of '90, where about 8 thousand people were poisoned with toxic poison. They had presented facts in front of Serbs, insisting that it was about a mass poisoning.
