The US envoy to the United Nations has said that North Korea has previously followed rocket launches with nuclear tests and warned Pyongyang that exploding another atomic device would be catastrophic for the impoverished country.
US Ambassador Susan Rice said :
"Clearly the potential for that pattern to persist is one that all members of the international community are mindful of and think would be a disastrous course for the North to pursue. It will only lead to the North's increased isolation."
North Korea followed its 2006 and 2009 missile launches with nuclear tests, prompting the 15-nation Security Council to impose sanctions on Pyongyang.
North Korea's celebrations was an attempt to show that the country will continue to demonstrate their power on a global platform.
North Korea's rocket splintered and crashed into the sea minutes after it was launched, South Korea's Defence Ministry said.
The delay in official confirmation from the North Korean authorities is becoming more and more awkward as the minutes and hours pass by.
