SEOUL, South Korea — North Korea launched an intermediate-range ballistic missile on Sunday, the first test since a new president took office in South Korea this past week and called for dialogue with the North.

The missile took off from the northwestern city of Kusong and flew more than 430 miles before landing in the sea between North Korea and Japan, the South Korean military said in a statement. Data on the launch was still being analyzed by the South to determine the type of missile.

Saying that North Korea had been “a flagrant menace for far too long,” the White House said in a statement late Saturday in Washington that the test served “as a call for all nations to implement far stronger sanctions” against Pyongyang.

“The United States maintains our ironclad commitment to stand with our allies in the face of the serious threat posed by North Korea,” the statement said.
