Full coverage: THAAD Deployment in South Korea

Demonstrations over the deployment of the US missile defense system THAAD continue. The latest protests come as the US Army Secretary Eric Fanning is on a three-day visit to the country. Yonhap news agency says he will speak with the US Army unit that will operate THAAD.

Residents of Seongju County -- where the controversial system will be installed -- have been holding rallies in front of the local government building for days. They are worried about the effects of radiation, and believe the deployment will undermine regional stability.
