The UN Security Council is holding anemergency, closed-door meeting to discuss North Korea's launch of a long-range rocket.
The Council started its meeting at 1:00pm (16:00 GMT) on Sunday in New York, following a request by South Korea, Japan and the US.
Pyongyang said the launch on Sunday morning was carrying a satellite.
The US and its allies believe Pyongyang's move was a cover to test a ballistic missile capable of carrying a nuclear warhead.
The rocket took off at around 9:00am Pyongyang time (00:30 GMT), according to the South Korean defence ministry.
Its pre-orbital flight arc was planned to traverse the Yellow Sea and further south to the Philippine Sea, with both South Korea and Japan threatening to shoot it down if it encroached on their territory.
US Strategic Command said that its "systems detected and tracked what we assess was a North Korean missile launch into space ... the missile was tracked on a southerly launch over the Yellow Sea".
Pyongyang pronounced the mission a "complete success," after claiming the rocket managed to put an observation satellite into orbit.
