The UN Security Council has strongly condemned North Korea’s launch of a long-range rocket.
After an urgent meeting in New York, the council said it would soon adopt a new sanctions resolution in response.
Pyongyang said it fired the rocket to place a satellite in orbit – but critics believe the real purpose was to test a ballistic missile.
Sunday’s launch comes weeks after North Korea held a fourth nuclear test – both acts violate UN resolutions.
Speaking after the closed-door talks, Venezuela’s UN envoy Rafael Ramirez, the current council president, said: “The members of the Security Council strongly condemn this launch.”
He called it “a serious violation of the Security Council resolution”.
US Ambassador to the UN Samantha Power said Washington would now “ensure that the Security Council imposes serious consequences” on Pyongyang.
“There can be no business as usual,” she said, adding that “we’ll come up with something tough”.
Ms Power’s words were echoed by Japanese envoy Motohide Yoshikawa, who said sanctions must be strengthened.
“The existing sanctions have not stopped North Korea from developing nuclear weapons,” he said.
The council meeting was requested by South Korea, Japan and the US.
