Thousands of people in North Korea on Thursday (February 14) held a mass rally in Pyongyang to celebrate the country's "successful" nuclear test.
Despite international warnings, North Korea conducted the third nuclear test on Tuesday (February 12).
Pyongyang said that the test was an act of self-defense against "U.S. hostility" and threatened stronger steps if necessary.
North Korea's third nuclear test in defiance of a U.N. resolution drew condemnation from around the world, including China, its only major ally.
The United Nations Security Council also condemned the underground test, saying the latest move by Pyongyang "is a grave violation" of relevant resolutions.
