North Korea has pledged unspecified retaliation against the South, after the final funeral ceremony for Kim Jong-il.
The North has pledged to shun South Korea’s Lee Myung-Bak government for eternity.
It made unspecified threats against the South and promised there would be no change in direction for their country under new leader Kim Jong-un.
The comments were made in an official statement from the powerful National Defence Commission.
The South Korean government will pay, it said, for the “unforgivable sins” of not allowing more South Koreans to travel to the North to pay their respects to Kim Jong-il, whose final funeral service was held on Thursday.
“We solemnly and proudly declare to foolish politicians in the world, including South Korean puppets, that they should not expect any changes from us,” the NDC statement said.
Kim Jong-un was declared “supreme leader of party and army and people” at Thursday’s massive memorial service.
“The world shall clearly see how the millions of our soldiers and people, who united firmly round great leader comrade Kim Jong-Un to transform sorrow into courage and tears into strength, will achieve the final victory,” the NDC statement added.
The world has been watching for any signs of change under the untested new leader, aged in his late 20s.
His father presided over a 1990s famine which killed hundreds of thousands, pursued a nuclear and missile program which brought international sanctions and resisted Chinese pressure to reform the crumbling state-directed economy.
Inter-Korean relations have been frosty since the conservative Mr Lee took office in February 2008 and linked major economic aid to nuclear disarmament.
Ties turned icy after Seoul accused Pyongyang of torpedoing a warship in March 2010 with the loss of 46 lives.
The North denied involvement but shelled a South Korean island in November 2010, killing four people including civilians.
“The scene of pan-national grieving by the people and military… shows the party, military and people united round the revolutionary leadership with one mind, and the invincibility of our socialist system and regime that cannot be toppled,” the NDC statement said.
The South’s Yonhap news agency said a statement issued in the name of the NDC, rather than attributed to an NDC spokesman, was rare.
