A diplomat close to the International Atomic Energy Agency says North Korea has expelled IAEA inspectors from its Yongbyon nuclear site.

The diplomat says the IAEA experts removed all agency seals from Yongbyon's nuclear facilities as well as surveillance cameras before leaving earlier Wednesday for Pyonyang, the country's capital

The North has also told the U.N. nuclear watchdog that it is reactivating its nuclear program.

The moves reflect anger at U.N. Security Council criticism of the country's latest missile launch.

The diplomat asked for anonymity because he was not authorized to release the information.
