nuclear test site

As has become custom, shortly after North Korea engages in some provocative activity, in this case its first ever hyrdogen bomb test, South Korea has traditionally responded with its own military drill, and today was no difference, with Yonhap reporting "that South Korea's military said Monday it conducted a combined live-fire exercise targeting North Korea's nuclear test site."

To be sure, it's not exactly clear how a "drill" can "target" a foreign military site, but we'll assume someone just used Google translate in this case.
