Sawt Falasteen - N. Korea's Kim supervises rocket launcher test: state media

The photos showed Kim, in a brown leather jacket, smiling with uniformed generals as he supervised the simultaneous launch of what appeared to be 18 projectiles.

The test involved "super-large multiple rocket sub-units", according to a report by the official Korean Central News Agency.

Analysts have suggested the nuclear-armed North could be testing and ramping up production of artillery and cruise missiles before sending them to Russia for use in Ukraine, something Pyongyang has angrily denied.

Images from the drill showed the 600mm multiple launch rocket system (MLRS), which North Korea has said can be fitted with nuclear warheads.

The exercises were meant to "serve as an occasion in clearly showing what consequences our rivals will face if they provoke us," the KCNA report said.

The drills showed that the North "will not hesitate to carry out a preemptive attack by invoking the right to self-defence at any time," it added.

KCNA said the rockets fired had "accurately hit an island target 365 km (226 miles) away."

On Thursday, South Korea's military said it had detected the launch of around 10 short-range ballistic missiles.

Seoul's military also put the range of the missiles launched at about 350 kilometres (217 miles), adding the launch was a "provocation".

US State Department spokesman Matthew Miller condemned the launches as "reckless behavior which poses a grave threat to the Korean Peninsula".

On Monday, North Korea attempted to put a second spy satellite into orbit, but it ended in a mid-air explosion.

That attempt came just hours after Seoul, Beijing and Tokyo held a rare trilateral summit, where they called for Pyongyang to give up its nukes.

A day after that, Pyongyang sent hundreds of trash-filled balloons across the border, in what it described as retaliation for balloons full of anti-Kim propaganda sent northwards by activists in the South.
