SEOUL (AFP): North Korea successfully launched a long-range rocket on Wednesday, in defiance of UN sanctions threats over what Pyongyang's critics have condemned as a disguised ballistic missile test.

North Korea said the three-stage rocket, which Pyongyang insists was solely aimed at placing a satellite in orbit, had achieved all its objectives.

"The launch of the second version of our Kwangmyongsong-3 satellite from the Sohae Space Centre ... on December 12 was successful," the Korean Central News Agency (KCNA) said.

"The satellite has entered the orbit as planned," it said.

Officials in South Korea and Japan confirmed that all three stages of the rocket appeared to have separated as scheduled.

However, South Korean defence ministry spokesman Kim Min-Seok cautioned that further analysis was required.

"There are many factors to determine whether it was successful or not ... we need more extensive analysis. We need more consultation with the United States since our own capability is limited," Kim told reporters.

There was no immediate comment from Washington. But Japan's government said it "cannot tolerate" the "extremely regrettable" launch, and Britain "deplored" North Korea's decision to go ahead rather try to improve its people's welfare.

In Seoul, President Lee Myung-Bak called an emergency meeting of his National Security Council to discuss the implications of the launch.

The North's decision to launch the rocket in winter had led analysts to suggest a political imperative behind the timing, which may have overruled technical considerations.

New leader Kim Jong-Un was believed to be extremely keen that the launch fell around the first anniversary of the death of his father and former leader Kim Jong-Il on December 17.

A previous launch of the same Unha-3 rocket in April had ended in failure, with the carrier exploding shortly after take-off.

A successful launch this time carries profound security implications, marking a major advance in the North's ability to mate an intercontinental ballistic missile (ICBM) capability with its nuclear weapons programme.

In October, North Korea had said it already possessed rockets capable of striking the US mainland -- a claim which many analysts dismissed as bluster.

According to tracking reports from the South Korean and Japanese armed forces, the rocket took off from the Sohae centre around 9:51 am (0051 GMT).

Japan, which had deployed missile defence systems to intercept and destroy the rocket if it looked set to fall on its territory, said it passed over its southern island chain of Okinawa around 12 minutes after take-off.

The first and second stages fell in the sea west and southwest of the Korean Peninsula, while the third splashed down 300 kilometres east of the Philippines."

North Korea had originally provided a December 10-22 launch window, but extended that by a week on Monday when a "technical deficiency" was discovered in the first-stage control engine.

Washington and its allies insist the launch is a disguised ballistic missile test that violates UN resolutions triggered by Pyongyang's two nuclear tests in 2006 and 2009.

In 2006, the Security Council imposed an embargo against North Korea on arms and material for ballistic missiles and weapons of mass destruction. It also banned imports of luxury goods and named individuals and companies to be subject to a global assets freeze and travel ban.

In 2009, it imposed a ban on North Korea's weapons exports and ordered all countries to search suspect shipments.

According to Japanese reports, Japan, the US and South Korea have agreed to demand the Security Council strengthen sanctions on North Korea to levels that match those on Iran.
