An emergency session of the United Nations Security Council ended without action Sunday after Japan and the US demanded a resolution in response to North Korea's launching of a high-altitude rocket.

The 15-country Security Council held a closed session to discuss the action, which Pyongyang claimed was a satellite launch.

The US and other powers have questioned the claim by saying no satellite was being placed into orbit. They called the launch a ballistic missile test.

After the meeting ended Sunday evening, Security Council President Claude Heller told reporters that member delegations planed to continue talks late Sunday. It was not clear when another formal meeting might be held.
