Several South Koreans were injured on Wednesday in a protest against the deployment of non-weapon materials and construction equipment onto the American missile defense system in South Korea.

Early in the day, a few dozen protesters staged a sit-in and blocked the passage of vehicles heading to the base for the Terminal High Altitude Area Defense (THAAD) system in the central town of Seongju, about 300 kilometers southeast of Seoul.

Police soon managed to disperse the crowd to make way for around 40 vehicles carrying power generator and construction materials.
