North Korea’s National Defense Commission has denied apologizing for a landmine explosion that injured two South Koreans. In a deal reached last week, North Korea expressed "regret" over the explosion. The agreement cooled hostilities between the two neighbors. South Korea has said it views the statement as evidence it finally persuaded North Korea to take responsibility for the early August incident. But in a statement Wednesday, the North Korean commission accused the South of misinterpreting the statement of regret.
