The Minister for Foreign Affairs, Charlie Flanagan, has expressed Ireland's condemnation of this morning's launch by North Korea of a long-range rocket.
It's widely believed to be a test for ballistic missile technology.
Meanwhile Nato's Secretary General says it's a blatant breach of five UN resolutions.
Jens Stoltenberg is demanding Pyongyang complies with international law.
The United Nations Security Council will meet later to discuss how to respond.
