A picture taken on April 25, 2024, shows activists of the NGO "Tvrdjava" ("Fortress"), Zvezdan Veljkovic, Borjana Vesic and Nikola Krstic, posing for a photo near a steel mill owned by Chinese company HBIS in the village of Radinac, near the eastern Serbian city of Smederevo. In the eight years since Chinese company HBIS bought a steel mill near the eastern Serbian city of Smederevo, residents say they have been plagued by heavy air pollution and thick red dust. Radinac, a village next to Smederevo, has become known as "red village", because everything is permanently coated in a layer of red dust. In the three villages near the mill, residents say that they have experienced throat irritation, unpleasant smells and continual soot coating their houses, clothes and bodies.
