U.N. experts say North Korea is exporting nuclear and ballistic missile technology and using intermediaries, shell companies and overseas criminal networks to circumvent U.N. sanctions.

The seven-member panel monitoring sanctions against North Korea said in a report obtained by The Associated Press late Thursday that its research indicates that Pyongyang is involved in banned nuclear and ballistic activities in Iran, Syria and Myanmar. It called for further study of these suspected activities and urged all countries to try to prevent them.

The 47-page report and a lengthy annex document sanctions violations reported by U.N. member states, including four cases involving arms exports and two seizures of luxury goods. The report also details the broad range of techniques that North Korea is using to try to evade sanctions imposed after its nuclear tests.
