SEOUL, South Korea — North Korea state media claimed Saturday that an elderly U.S. tourist detained for more than a month has apologized for alleged crimes during the Korean War and for “hostile acts” against the state during a recent trip.

North Korean authorities released video showing 85-year-old Merrill Newman reading his alleged apology, which was dated Nov. 9 and couldn’t be independently confirmed.

Pyongyang has been accused of previously coercing statements from detainees. There was no way to reach Newman and determine the circumstances of the alleged confession. But it was riddled with stilted English and grammatical errors, such as “I want not punish me.”

The statement, carried in the North’s official Korean Central News Agency, said the war veteran allegedly attempted to meet with any surviving soldiers he had trained during the Korean War to fight North Korea, and that he admitted to killing civilians and brought an e-book criticizing North Korea.

Newman, an avid traveler and retired finance executive, was taken off a plane Oct. 26 by North Korean authorities while preparing to leave the country after a 10-day tour. His traveling companion seated next to him, neighbor and former Stanford University professor Bob Hamrdla, was allowed to depart.

Newman’s son, Jeffrey Newman, said his father wanted to return to the country where he spent three years during the Korean War.
