A leading newspaper of the Democratic People's Republic of Korea (DPRK) on Monday accused South Korea of lying in its propaganda over last month's Yonphyong Island shelling incident.

South Korea's claim that the DPRK provocated the incident is "a lie to the world," Rodong Sinmun said in a commentary on the meeting of top U.S., Japanese and South Korean diplomats in Washington on Dec. 6 .

South Korea used the incident as an excuse to accelerate its confrontation with the DPRK with the help of other countries, it said.

The move, the commentary said, has intensified the already tense situation on the Korean Peninsula and brought dark clouds of nuclear war to the peninsula.

South Korea would suffer "painful consequences" of the tension while the outsiders would benefit, and South Korea's action to "jugulate" fellowmen with outsiders is an intolerable "move of traitor," it said.

It was the first time that DPRK media commented on the Dec. 6 meeting of the top diplomats of South Korea, Japan and the United States, who threatened to jointly confront any "provocation and threats" of the DPRK in a post-meeting statement.

Tensions on the Korean Peninsula have been heightened since South Korea and the DPRK exchanged artillery fire on Nov. 23.

After the incident, South Korea and the United States staged joint naval drills from Nov. 28 to Dec. 1 in waters west of the peninsula. On Dec. 3, Japan and the United States launched their biggest-ever joint military exercises at bases across Japan and in the air and on waters around them, with South Korea taking part as an observer.
