Syria in a letter "stated its readiness to have a meeting with agency safeguards staff in Damascus in October," International Atomic Energy Agency (IAEA) head Yukiya Amano told a regular meeting of its board in Vienna.

"Syria's letter stated that the purpose of the meeting would be 'to agree on an action plan to resolve the surrounding issues in regards to (the) Dair Alzour site,'" Amano said, according to the text of his remarks.

On June 9, the IAEA decided to report Syria's to the UN Security Council after concluding that the site was "very likely" an undeclared reactor. There are also suspicions it was built with help from North Korea.

Amano said that the nuclear watchdog has proposed the meeting takes place on October 10-11.

"Iran demonstrated greater transparency than on previous occasions" during the trip last month, International Atomic Energy Agency (IAEA) chief Yukiya Amano told a regular meeting of the agency's board of directors in Vienna.

But Tehran "is not providing the necessary cooperation to enable the agency to provide credible assurance about the absence of undeclared nuclear materials and activites in Iran," he said.

This would allow the IAEA "to conclude that all nuclear material in Iran is in peaceful activities," Amano said, according to the text of his remarks given to reporters.

Many Western nations suspect Iran is working towards developing nuclear weapons, and Tehran's refusal to suspend certain suspicious activities has led to four rounds of UN Security Council resolutions.

As stated in a draft report by the agency seen by AFP earlier this month, Amano said the agency was "increasingly concerned" about the possible existence of undisclosed nuclear activities involving "military-related" organisations.

These included "activities related to the development of a nuclear payload for a missile, about which the Agency continues to receive new information," Amano said.
