First day of the June 1990 Mineriad in Romania. At least 240 strikers and students are arrested or killed in the chaos ensuing from the first post-Ceaușescu elections.

The June 1990 Mineriad was the suppression of anti-National Salvation Front (FSN) rioting in Bucharest, Romania by the physical intervention of groups of industrial workers as well as coal miners from the Jiu Valley, brought to Bucharest by the government to counter the rising violence of the protesters. This event occurred several weeks after the FSN achieved a landslide victory in the May 1990 general election, the first elections after the fall of the communist regime of Nicolae Ceaușescu. Many of the miners, factory workers, and other anti-protester groups, fought with the protesters and bystanders. The violence resulted in some deaths and many injuries on both sides of the confrontations. Official figures listed seven fatalities and hundreds of injured, although media estimates of the number killed and injured varied widely and were often much higher.
