North Korea fired an ICBM toward the East Sea on Thursday (Seoul time), ending its self-imposed moratorium on nuclear and long-range missile testing that has been in place since late 2017.
The US earlier said the North may launch an ICBM, noting its two recent missile tests on February 27 and March 5 (Seoul time) had involved a new ICBM system.
"This launch is a brazen violation of multiple UN Security Council resolutions and needlessly raises tensions and risks destabilizing the security situation in the region," she said.
"This action demonstrates that the DPRK continues to prioritize its weapons of mass destruction and ballistic missile programs over the well-being of its people."
She added the U.S. was working in close coordination with its allies to assess the situation.
"We urge all countries to hold the DPRK accountable for such violations and call on the DPRK to come to the table for serious negotiations," she said.
The White House spokesperson also urged Pyongyang to engage in dialogue.
"The door has not closed on diplomacy, but Pyongyang must immediately cease its destabilizing actions. The United States will take all necessary measures to ensure the security of the American homeland and Republic of Korea and Japanese allies," the released statement said.
The call for North Korea's return to dialogue was echoed by the State Department.
"We stand with the international community to call on the DPRK to refrain from further provocations and engage in sustained and substantive dialogue," department spokesperson Ned Price said in a statement.
"We have been and will continue to coordinate closely with our allies and partners to address the threats posed by the DPRK, and to advance our shared objective of the complete denuclearization of the Korean Peninsula," he added.
North Korea remains unresponsive to U.S. overtures. It has avoided denuclearization talks since late 2019. (Yonhap)
