A United Nations expert panel alleges that North Korea exported banned nuclear and ballistic missile technology to several rogue nations. The 75-page report, complied by a seven-member panel reporting to the United Nations Security Council, states that North Korea is involved in nuclear and ballistic missile-related activities in certain countries, including Iran, Syria and Myanmar and that special attention should be given by all member- countries to inhibit such activities. The report, which was released this week, had been delayed from publication for six months by China, a friendly nation to North Korea, according to a diplomat familiar with the case.
