North Korea confirms 'successful' new ballistic missile test

The state-run KCNA news agency said the weapon was now ready to be deployed for military action.

The White House said the missile had a shorter range than those used in North Korea's last three tests.

It comes a week after North Korea tested what it said was a new type of rocket capable of carrying a large nuclear warhead.

Last Monday, the UN Security Council again demanded that Pyongyang conduct no further such tests.

It stressed the importance of North Korea "immediately showing sincere commitment to denuclearisation through concrete action".

The Council is now scheduled to meet behind closed doors on Tuesday - a meeting requested by the US, South Korea and Japan.

'Reckless and disturbing'

North Korean leader Kim Jong-un oversaw the launch of the Pukguksong-2 missile on Sunday, KCNA reports, adding that he had "approved the deployment of this weapon system for action."

South Korea's foreign ministry earlier said the launch was "reckless and irresponsible", while US Secretary of State Rex Tillerson described it as "disappointing" and "disturbing".

The latest missile flew about 560km (350 miles) towards the Sea of Japan, South Korea's Joint Chiefs of Staff said. Last week's missile travelled about 700km.

Japanese news agencies said the missile probably fell into the sea outside Japanese waters.

Japan's Chief Cabinet Secretary Yoshihide Suga told a news conference a protest had been lodged with North Korea.

• Have North Korea's missile tests paid off?

North Korea is known to be developing both nuclear weapons - it has conducted five nuclear tests - and the missiles capable of delivering those weapons to their target. Both are in defiance of UN sanctions.

South Korea said the latest test was conducted in Pukchang, in the west of the country. A missile exploded soon after take-off from Pukchang last month.

Earlier on Sunday, the North's state-run media had said it would continue to launch more "weapons capable of striking" the US.

In early May, the US said a missile defence system it had installed in South Korea was now operational.

The Thaad system can intercept North Korean missiles, although full operational capability is still some months away. North Korea and its ally China have condemned the installation of the system.

However, there is no sign that Thaad was used against the missile tested on Sunday.

Newly-installed South Korean President Moon Jae-in, who is seeking deeper engagement with the North, has convened an urgent meeting of his national security council in response.

Kim defies the pressure: Steve Evans, BBC News, Seoul

This would be the 10th detected missile launch by North Korea this year - outside experts agree that it's making progress in its stated aim of having the ability to strike the mainland US with nuclear weapons.

Though it's not there yet, the latest tests have been of missiles capable of reaching American bases in the Western Pacific, albeit with some failures.

There is intense pressure on Kim Jong-un from the US, which is seeking the help of China. Repeated and more frequent testing of missiles, despite prohibition by the United Nations, indicates the North Korean leader feels able to defy that pressure.
