The context of reading the news, in general, will help you to see that the article cited is an outlier, or is erroneous, or is a side-show:
BBC News - 'No plans to withdraw' UK diplomats from North Korea
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
I think it's Seoul too- they warned the embassies in Pyongyang first, then warned foreigners in South Korea- tourists, people working in Seoul second, trying to ramp up the tension and maybe deter some tourists.
Looks like we are heading back towards my original thought on this.
