SEOUL, South Korea: North Korean leader Kim Jong Un called for more weapons tests targeting the Pacific Ocean, Pyongyang announced Wednesday, a day after his nation for the first time flew a ballistic missile designed to carry a nuclear payload over Japan.

Tuesday’s aggressive missile launch — likely the longest ever from North Korea — over the territory of a close U.S. ally sends a clear message of defiance.

Pyongyang’s official news agency said it was a Hwasong-12 intermediate range missile that the North first successfully tested in May and threatened to fire into waters near Guam earlier this month.

Kim expressed “great satisfaction” over the launch that he called a “meaningful prelude” to containing Guam, which is home to key U.S. military bases that North Korea finds threatening, the agency said. He also said the country will continue to watch “U.S. demeanors” before it decides on future actions.

Kim also said it’s “necessary to positively push forward the work for putting the strategic force on a modern basis by conducting more ballistic rocket launching drills with the Pacific as a target in the future.”

In an emergency meeting Tuesday on the missile test, the U.N. Security Council said it “strongly condemns” North Korea’s actions and reiterated demands for Pyongyang to halt its ballistic missile and nuclear weapons programs.

In a statement, U.S. President Donald Trump said North Korea had signaled its “contempt for its neighbors” and that “all options are on the table” in terms of a U.S. response.
