At 8 am on March 29, construction vehicles attempted to drive through the village of Soseong-ri to enter the deployment site for the THAAD missile system. The vehicles were reportedly carrying equipment used for geological surveys, possibly for the purpose of conducting an environmental impact assessment of the site.
At approximately 8:30am, village residents and Won Buddhist ministers blocked the vehicles from going any farther by holding a sit-in protest in the middle of the road. Close to 9:00am, hundreds of police officers surrounded the village residents and ordered them to disperse. The residents, however, stood their ground, and tensions with the police lasted for one hour.
At noon, the construction vehicles attempted yet again to pass through the village, but the residents quickly resumed their sit-in protest to block them. By about 1:30pm, all police and construction vehicles, unable to gain entry, retreated from the village. At 2:00pm, the village residents held their weekly Wednesday protest rally at the Soseong-ri village center.
