South Korea says rival North Korea 'must disappear soon'

The rhetorical battle between the two Koreas intensified after a South Korean official said that North Korea 'must disappear soon'.

The comments were made by South Korean Defense Ministry spokesman Kim Min-seok after a series of sexist and racist slurs made by North Korea against South Korea and the United States leaders.

Pyongyang's state media had likened South Korean President Park Geun-hye to an 'old prostitute' and U.S. President Barack Obama to a 'monkey' in recent dispatches, Fox News reports.

Min-seok told reporters at a briefing in Seoul that North Korea is not a real country and exists for the benefit of only one person, making a reference to dictator Kim Jong Un.

He said the North has no human rights or public freedoms.

According to the report, Pyongyang has been ramping up its rhetoric against Seoul and Washington since Obama and Park met in Seoul last month.

During that visit, Obama said that it might soon consider further sanctions against the North and that the U.S. will not hesitate to use its military might to defend its allies, the report said.

South Korea has called the North's verbal insults against Park immoral and unacceptable.

The U.S. State Department described the North's racist slurs against Obama as 'disgusting'.
