North Korea fired a suspected intermediate-range ballistic missile on Sunday.

“No immediate threat was assessed for the Marianas from the reported launch,” said Guam Homeland Security Advisor, Esther Aguigui. “Events such as these will continue to be monitored by our office, while working with local, military, and federal partners.”

The launch was the North’s first this year.

It comes two months after the North claimed to have tested engines for a new harder-to-detect missile capable of striking distant U.S. targets in the region.

South Korea’s Joint Chiefs of Staff said in a statement that it detected the launch of a ballistic missile of an intermediate-range class from the North’s capital region on Sunday afternoon. It said the missile flew toward the North’s eastern waters.
