Earlier, they held a press conference.

They denounced the decision of the U.S. and the puppet regime to deploy THAAD, holding slogan boards opposing THAAD deployment.

In a press release they said that it is impossible to risk the people's life for the sake of the U.S. forces.

They will continue fighting against THAAD deployment which will bring the danger of a war to the Korean peninsula and serious economic bankruptcy with the sit-in strike protesting against the unilateral decision to deploy THAAD as a prelude, the press release noted.

It said that they would stage the above-said strike demanding the withdrawal of the decision of THAAD deployment and conduct information service for letting people know about the danger of the deployment outside the Ryongsan U.S. military base for two days.
