NORTH Korea today vowed unspecified retaliation against South Korea for its perceived insulting response to the death of late leader Kim Jong Il.

The threat came in a statement on the official North Korean news agency and was also read on state television.



"We will make the [South Korean leader] Lee Myung-Bak traitor group pay till the end for the eternally unforgivable sins they committed on the occasion of the state funeral," it said.



The TV highlighted the comment in a sub-title under the announcer, which was repeated for about 10 minutes.
