North Korean leader orders further nuclear tests

Seoul

Since the joint drills began Monday, the North has issued daily warnings and statements, talking up its nuclear strike capabilities and threatening to turn Seoul and Washington into 'flames and ashes'.

Just days after he was photographed posing in front of what state media described as a miniaturised nuclear warhead, Kim said the weapon required further testing.

Overseeing a ballistic missile launch yesterday, Kim ordered 'more nuclear explosion tests to estimate the destructive power of the newly produced nuclear warheads', the North's official KCNA news agency said.

Experts are divided as to just how far the North may have gone in shrinking warheads to a size capable of fitting on a ballistic missile - a major step forward in strike capability that would present a heightened threat to South Korea, other countries in the region and, eventually, the US mainland.

According to KCNA, yesterday's launch of two short-range ballistic missiles, which traversed the eastern part of the country before falling into the East Sea (Sea of Japan), was part of a nuclear strike exercise.

The aim was to simulate conditions for 'exploding nuclear warheads from the preset altitude above targets in the ports under enemy control', the agency said.

Watching the exercise, Kim reiterated an earlier threat to launch an immediate nuclear attack if the 'sabre-rattling' South Korea-US drills should harm 'even a single tree or a blade of grass' on North Korean territory.

"I will issue a prompt order to launch attack with all military strike means," he said.

Military tensions on the divided Korean peninsula have been on the rise since the North carried out its fourth nuclear test in January, followed by a long-range rocket launch last month.

South Korea and the United States responded by scaling up their annual joint drills, which Pyongyang has always condemned as provocative rehearsals for invasion.

The North's anger has been fuelled this year by reports that the drills included a 'decapitation strike' scenario in which the North Korean leadership and command structure is taken out at the start of any conflict.

In light of such drills, "our self-defensive countermeasures should adopt a more preemptive and offensive mode," Kim said.

The UN Security Council responded to the North's latest nuclear test and rocket launch by adopting tough, new sanctions, which Pyongyang condemned as a 'gangster-like' provocation orchestrated by the United States.

Reacting to Kim's call for more nuclear tests, South Korea today said the North Korean leader was being 'rash' and displaying his ignorance of international opinion.
