The International Atomic Energy Agency says it is now unlikely to send a delegation to North Korea, after Pyongyang stated it is no longer bound by an agreement with the United States not to test missiles and nuclear devices.

Its Spokesperson Gill Tudor made the announcement late last evening.Earlier in the day, Pyongyang said it was breaking off a bilateral agreement to halt its nuclear activities and allow IAEA inspectors to enter the country after the U.S. suspended much needed food aid.

North Korea's Foreign Ministry vowed to continue trying to fire a long-range rocket into space to place what it said was a weather satellite into orbit. It also vowed unspecified retaliation now that the agreement with the U.S. is no longer in place.
