Joint Comprehensive Plan of Action

International Atomic Energy Agency chief Rafael Grossi on Tuesday called on Iran to adopt "concrete" measures to help bolster cooperation on the country's nuclear programme.

Israel and Iran accused one another Sunday at the United Nations of being the main threat to peace in the Middle East, each calling on the Security Council to impose sanctions on their sworn enemy.

The U.N. nuclear watchdog has voiced growing concern over Iran's ability to build nuclear weapons, fuelled by recent public statements in the country, according to a confidential report seen by AFP on Monday.

Late last month, as part of its monitoring of Iran's nuclear program, the International Atomic Energy Agency reported trace amounts of uranium at 84% enrichment. That's important, because 90% enrichment is required to produce a nuclear weapon.

The European Union and Iran agreed on Saturday to resume negotiations in Vienna in the coming days over Tehran's tattered nuclear deal with world powers.

The agreement could help relieve tensions after the talks stalled for months, while Iran enriches uranium closer than ever to weapons-grade levels under decreasing international oversight.

Germany, the United Kingdom and France on June 9 urged Iran to "cease its nuclear escalation" and "urgently conclude the deal currently on the table" to revive the 2015 nuclear agreement.

"There has been a viable deal on the table since March," they said in a joint statement.

Iran condemned as "not fair" Tuesday a report by the UN nuclear watchdog on traces of nuclear material found at three undeclared sites.

The comments came with talks deadlocked since March on reviving a 2015 nuclear agreement between Tehran and world powers.

Five months after they were suspended, international talks on Iran's nuclear programme will restart on Monday in Vienna with analysts foreseeing major obstacles to any speedy resumption of the 2015 nuclear deal.

Turkish Foreign Minister Mevlüt Çavuşoğlu spoke on Oct. 21 over the phone with his counterparts from both Iran and the United Arab Emirates (UAE).

Çavuşoğlu and Iranian Foreign Minister Hossein Amir-Abdollahian discussed regional issues, especially developments related to Afghanistan and Syria, as well as bilateral relations, said a Foreign Ministry statement.
