North Korea executed its nuclear envoy to the United States as part of a purge of officials who steered negotiations for a failed summit between leader Kim Jong Un and U.S. President Donald Trump.”

“Previously, some North Korean officials who were reported to have been executed or purged reappeared later with new titles.”

Was the reporting wrong, or were those officials resurrected? Dunno. Kim-Beric Don-Darrion was not available to the press.
