North Korea said on Friday (October 4) it will continue with its nuclear development despite pressures from the international community.

The United States and South Korea signed a new pact to deter North Korea's potential use of nuclear arms and other weapons of mass destruction amid growing threats from Pyongyang, their defence chiefs said on Wednesday (October 2).

The statement also targeted South Korean President Park Geun-hye, saying her "disgusting acts leave even young pupils of North Korean primary school sceptical of her ability as president".

South Korean government on Friday said the statement read by KRT was an "irrational act".

North Korea conducted its third nuclear test in February, two months after successfully launching a long-range rocket that put an object into space which Pyongyang says was a satellite.

The launch resulted in tougher U.N. sanctions against the impoverished and isolated North by trying to cut off its arms trade, which had been a lucrative source of income, and disrupt financial transactions in support of those activities.
