PYONG YANG — In a major show of defiance to the international community, North Korea fired a ballistic missile over the northern Japanese island of Hokkaido Friday.

The launch is the second to fly over Japan in less than a month, and the first since North Korea’s sixth nuclear test and new United Nations sanctions on the country.

North Korean state media has yet to reference the launch, but a commentary published in the Rodong Sinmun newspaper Friday said “no matter how strong the pressure is, it doesn’t work on us.”

Tokyo and Washington will be seeking to up that pressure at the United Nations Friday, with the two governments calling a snap meeting of the Security Council for Friday afternoon, ahead of the General Assembly next week.

Speaking after the launch, the first since North Korea’s sixth nuclear test, Japanese Prime Minister Shinzo Abe said the launch was “totally unacceptable” and went against “the international community’s strong, united will for a peaceful solution.”

Friday’s missile test follows the release of a statement Wednesday, in which the North Korean state news agency KCNA threatened the “four islands of the (Japanese) archipelago should be sunken into the sea by the nuclear bomb of Juche,” referring to the ruling ideology of North Korea.

The launch also seemed to be intended to send a message to the US, flying a distance equivalent to that from North Korea to Guam, the US territory that has come under threat from Pyongyang in recent weeks.

Launch and response

North Korea’s latest missile was fired from the district of Sunan in the North Korean capital of Pyongyang, home to the country’s main airport, the South Korean military said.

Initial US assessments suggested North Korea fired an intermediate-range ballistic missile, similar to that fired over Japan last month.

The missile flew about 3,700 kilometers (2,300 miles) and reached an altitude of 770 kilometers (480 miles) before landing in the Pacific Ocean. Guam is 3,380 kilometers (2,100 miles) from North Korea.

Friday’s missile flew the furthest of any North Korean intermediate-range missiles, though previous launches have used lofted trajectories, where missiles fly much higher over a shorter distance. By comparison, an intercontinental ballistic missile launched in July flew 3,700 kilometers (2,300 miles) high and traveled a distance of 1,000 kilometers (621 miles).

In response to North Korea’s launch, South Korea carried out a “live fire drill” that included a missile launch which the South Korean Joint Chiefs of Staff said was capable of striking the Sunan airport launch site near Pyongyang used for today’s launch.

The South Korean missile, which was launched from the country’s east coast while the North Korean missile was still in the air, was “a show of force in response to North Korea’s latest provocation,” a South Korean official told CNN.

A second missile that was fired at the same time failed and “sank into the sea off the east coast,” an official said.

Park Soo-hyun, spokesman for South Korean President Moon Jae-in, said the country’s military had been ordered “to prepare a stern measure that can effectively counter North Korea’s increasing nuclear and military threats.”

“North Korea’s firing of yet another ballistic missile is a clear violation of (UN Security Council) resolutions and a very serious and grave challenge to international peace and security,” the South Korean government said in a statement.

NATO Secretary General Jens Stoltenberg said the launch was “another reckless breach of UN resolutions” and a “major threat” to international peace and security “which demands a global response.”

In regularly scheduled press conference Friday, Chinese Foreign Ministry spokeswoman Hua Chunying reemphasized Beijing’s “resolution” on pushing for the denuclearization of the Korean Peninsula.

“China has strictly and comprehensively implemented the resolutions of the UN Security Council,” Hua said, adding the country has “paid a great price and made sacrifices.”

Japan on high alert

Friday’s missile test set off sirens as a government warning, known as the J-Alert, went out to citizens across a broad swath of northern Japan.

“The government is advising people to stay away from anything that could be missile debris,” NHK reported.

In a statement, US Secretary of State Rex Tillerson said the missile test was the second time the people of Japan “have been directly threatened in recent weeks.”

“The international community needs to unite and send clear message after North Korea’s dangerous provocation,” Abe told reporters. “We must let North Korea understand there is no bright future for North Korea if it continues in this way.”

He said the Japanese government tracked the launch of the missile and “took all possible measures.”

Japan and the US have requested the UN Security Council hold “urgent consultations” at 3 p.m. ET Friday, according to the Ethiopian Mission to the UN. Ethiopian Ambassador Tekeda Alemu is the current UN Security Council president.

Need for more pressure

The launch came just hours after North Korea responded to the United Nations Security Council’s unanimous approval of additional sanctions by threatening to “sink” Japan and reduce the US mainland into “ash and darkness.”

Those sanctions were prompted by North Korea’s sixth nuclear test that occurred on September 3, which Pyongyang said was a successful test of a hydrogen bomb.

That explosion created a magnitude-6.3 tremor, making it the most powerful weapon Pyongyang has ever tested.

The nuclear test prompted discussions inside South Korea about the the redeployment of US tactical nuclear weapons in the country, an idea that the majority of the country’s citizens approve of, according to recent polls.

But on Thursday, South Korean President Moon Jae-in dismissed the possibility, warning it could “lead to a nuclear arms race in northeast Asia.”

Both Abe and Tillerson called for an intensifying of pressure on North Korea, including the full implementation of the new UN sanctions.

“These continued provocations only deepen North Korea’s diplomatic and economic isolation,” Tillerson said.

Rapid pace

2017 has been a year of rapid progress for North Korea’s missile program.

Less than six years into his reign, Kim Jong Un has tested more missiles than his father and grandfather combined. And this year has been no exception.

Prior to its most recent launch, the country has fired 21 missiles during 14 tests since February, further perfecting its technology with each launch.
