North Korea has reportedly executed its special envoy to the United States, after President Trump walked away from a summit with North Korean leader Kim Jong-un in February without a deal on denuclearization. A major South Korean newspaper reports the envoy, Kim Hyok-chol, was shot to death by a firing squad in March at an airfield outside of Pyongyang along with four other North Korean Foreign Ministry officials, and that a translator at the summit was sent to a forced labor camp for committing a translation mistake. This comes as Kim’s sister is said to be “lying low” on her brother’s orders in the wake of the summit’s collapse. She hasn’t been seen in public since.
