The UN Security Council has condemned North Korea for launching a rocket in defiance of a UN ban.
Calling the launch "a clear violation of Security Council resolutions", the council said it would consider an "appropriate response".
The statement came after closed consultations in New York.
The US and its allies view the launch as a disguised test of ballistic missile technology. North Korea says its aim was to launch a satellite.
North Korea was banned by the UN from ballistic missile tests after nuclear tests in 2006 and 2009.
The US says Pyongyang will face "consequences" for the launch, calling it a "highly provocative act that threatens regional security".
