North Korea denies it apologized over land mine blast that maimed 2 South Koreans

North Korea on Tuesday denied Seoul's claim that Pyongyang's recent expression of "regret" after a marathon negotiating session is an apology for a mine explosion that maimed two South Korean soldiers.

The statement by Pyongyang's powerful National Defense Commission, the first explicit denial of the key part of an accord heralded by the South as a mini-breakthrough for the bitter rivals, muddies the prospects for better ties between the Koreas and further belies Seoul's claim that it successfully pushed the North in the talks last week to take responsibility for the blast.

Seoul must stop saying the North apologized or face unspecified consequences, the North said.

North Korea's vague expression of "regret" after three days of talks last week over the South Korean soldiers' injuries, not over laying the mines, allowed the two Koreas to back away from threats of war. Seoul responded by turning off cross-border loudspeaker broadcasts critical of the North's political system.

North Korea in its statement Tuesday also criticized South Korea's recent live-fire drills with the U.S.
