UN Secretary-General António Guterres urged President Joe Biden's Administration to lift or waive all sanctions imposed on Iran in accordance with the 2015 deal aimed at preventing Tehran from developing a nuclear weapon.

In a report to the UN Security Council, Guterres also urged the United States to "extend the waivers with regard to the trade-in oil with the Islamic Republic of Iran, and fully renew waivers for nuclear non-proliferation projects."

Guterres' appeal to the US comes amid talks to revive the deal by virtue of which Iran accepted restrictions on its nuclear program in return for the lifting of many foreign sanctions imposed on it.

Guterres said: "I appeal to the United States to lift or waive its sanctions outlined in the plan," and he also called on Iran to return to the full implementation of the deal.

The 15-member Security Council will discuss the Secretary-General's biannual report on the implementation of the 2015 resolution that guarantees the nuclear deal between Iran, the United States, France, Britain, Germany, Russia, and China.
