Tehran, February 22 (QNA) - The International Atomic Energy Agency (IAEA) said that Iran has stopped a team of inspectors from visiting the Parchin military site, south of Tehran, despite "intensive efforts". The UN nuclear watchdog said that after two days of talks, its team was returning from Iran without a deal on a document "facilitating the clarification of unresolved issues" in connection with Tehran's nuclear program.
The first round of discussions in January also failed to produce a result.
"It is disappointing that Iran did not accept our request to visit Parchin," IAEA Director General Yukiya Amano said in a statement.
It is suspected that Parchin was the site where explosives related to nuclear weapons may have been tested in recent years.
The inspectors had sought to clarify the "possible military dimensions" of Iran's nuclear program.
Iran insists it is purely for peaceful purposes, but the West suspects the program has military implications.
Meanwhile, Iran's envoy to the Vienna-based IAEA said Tehran expected to hold further talks with the agency.
Ali Asghar Soltanieh was quoted by Iran's (ISNA) news agency as saying the latest discussions had been intensive and that talks would continue in the future.
The inspectors' evaluation of their visits may form part of the next report on Iran's nuclear program, expected later in February.
Last November, the IAEA said it had information suggesting Iran had carried out tests "relevant to the development of a nuclear explosive device".
This led to decisions by the United States and the European Union to tighten sanctions against Tehran, including measures targeting the country's oil industry.
Tensions have also risen further over speculation that Israel may carry out a military strike on Iran's nuclear facilities. (QNA)
