it is surrounded by electric fences. normally there are guards in watchtowers who are there, armed, ready to react every 2a hours. this happened on new year's day. it has happened in the same area in the last year, so there are questions about the security and surveillance of the border area in this east coast part of south korea. what appears to have happened is an alert was raised about 6:a0am on new year's day and then a search was made for about three orfour hours. they did not find the individual and that individual has then made it into north korea. one of the things we do know, and certainly one of my sources is telling me, is it is a civilian but we don't know if it is a south korean citizen or whether or not it was a north korean defector who was here in the south, who may have wanted to try and go back north. coronavirus is continuing to cause major disruption for travellers worldwide.
