North Korean media on Sunday slammed South Korea for its participation in the passing of a UN resolution condemning the Norths human rights abuses, Yonhap news agency reported.

The resolution was passed on December 17 at the UN General Assembly and condemned North Korea's "systematic, widespread and gross violations of human rights".

Uriminzokkiri, the North's external propaganda website, said the "South Korean authorities expressed support for the US' anti-Pyongyang ploy to condemn the human rights situation," adding that Seoul showed a "double-faced attitude".

"In front (of us), (South Korea) talks of trust and harmony, while it follows the foreign forces' ploy behind our back," it said, according to Yonhap.

Another outlet, Maeari, warned that "followers of the US will pay dearly for their provocative, malign acts."

The North's rhetoric came from external media, rather than official channels.

The resolution came amid efforts by Seoul to build mutual trust and reduce military tensions.
