North Korea fires Scud-class ballistic missile, Japan protests

North Korea fired at least one short-range ballistic missile on Monday that landed in the sea off its east coast, the latest in a fast-paced series of missile tests defying world pressure and threats of more sanctions.

The missile was believed to be a Scud-class ballistic missile and flew about 450 km (280 miles), South Korean officials said. North Korea has a large stockpile of the short-range missiles, originally developed by the Soviet Union.

Monday's launch followed two successful tests of medium-to-long-range missiles in as many weeks by the North, which has been conducting such tests at an unprecedented pace in an effort to develop an intercontinental ballistic missile (ICBM) capable of hitting the mainland United States.

North Korea was likely showing its determination to push ahead in the face of international pressure to rein in its missile program and "to pressure the (South Korean) government to change its policy on the North," South Korea's Joint Chiefs of Staff spokesman Roh Jae-cheon said.

It was the third ballistic missile test launch since South Korea's liberal President Moon Jae-in took office on May 10 pledging to engage with the reclusive neighbor in dialogue.

Moon says sanctions alone have failed to resolve the growing threat from the North's advancing nuclear and missile program.

The missile reached an altitude of 120 km (75 miles), Roh said.

"The assessment is there was at least one missile but we are analyzing the number of missiles," he said.

North Korea, which has conducted dozens of missile tests and tested two nuclear bombs since the beginning of 2016 in defiance of U.N. Security Council resolutions, says the program is necessary to counter U.S. aggression.

The White House said President Donald Trump had been briefed about the launch. The U.S. Pacific Command said it tracked what appeared to be a short-range ballistic missile for six minutes and assessed it did not pose a threat to North America.

Trump portrayed the missile test as an affront to China in a morning post on Twitter. "North Korea has shown great disrespect for their neighbor, China, by shooting off yet another ballistic missile...but China is trying hard!" he wrote.

U.S. Defense Secretary Jim Mattis, asked what a military conflict with North Korea might look like if diplomacy failed, warned on Sunday it would be "probably the worst kind of fighting in most people's lifetimes".

"The North Korean regime has hundreds of artillery cannons and rocket launchers within range of one of the most densely populated cities on Earth, which is the capital of South Korea," Mattis told CBS news program "Face the Nation".

"And in the event of war, they would bring danger to China and to Russia as well," he said.
