Iran voluntarily allowed the International Atomic Energy Agency (IAEA) to replace the damaged cameras at Karaj's TESA site with the new ones in the wake of a recent agreement with the IAEA.

Iran's voluntary measure is meant to help resolve misunderstandings with the IAEA.

Acting on its own initiative, the country had begun allowing the IAEA's experts to change the damaged devices since the country had completed the "main part" of the necessary investigations, IRNA cited Iran's Nournews agency as reporting on Wednesday.

Iran, however, had refused in September to allow the IAEA to gain access to a number of cameras that had been damaged during a terrorist operation targeting the TESA Karaj Complex, a centrifuge component manufacturing workshop in north-central Iran.

The Islamic Republic of Iran's refusal was based on the fact that the country needed to complete some legal-security investigations into the incident.

The Iranian initiative was also motivated by the IAEA's condemnation of such sabotage operations, the Nour news agency which is affiliated to the country's Supreme National Security Council (SNSC) further said.
