Vienna- Inspectors of the International Atomic Energy Agency (IAEA) started Tuesday to reinstall seals and cameras in its plutonium reprocessing plant, a source close to the agency said.

On Monday, the Vienna-based agency announced that the reclusive Stalinist state had reversed its ban on IAEA inspections, after the United States struck the country from its terrorism blacklist on Saturday.

In September, North Korea had ordered the IAEA to remove monitoring technology from its plutonium reprocessing facility in its Yongbyon nuclear complex.

An IAEA official said that the process of monitoring North Korea's nuclear installations had resumed. He could not confirm whether North Korea had also restarted unloading nuclear fuel from its reactor, as announced by Pyongyang on Monday.

IAEA experts are stationed permanently in Yongbyon to monitor the freeze of the complex that North Korea has agreed to in six-party talks with the US, China, South Korea, Japan and Russia, in exchange for improved diplomatic and economic relations, including energy and humanitarian aid. (dpa)
