Saudi Arabia fully supports the U.S.-Iran nuclear talks and hopes for positive results, the kingdom's foreign minister Prince Faisal bin Farhan Al-Saud said on Wednesday.

Plus, Badar Khan Suri, the Georgetown University scholar who was targeted for deportation by the Trump administration is released from federal custody.

President Trump on Thursday teased that the U.S. and Iran were inching closer to an agreement on a nuclear deal, saying the two sides were in “very serious negotiations” for “long-term peace.”

Iran has said it doesn't seek a nuclear weapon. But the United States is pressing Iran for full denuclearization, urging a voluntary end to enrichment and the abandoning of centrifuges and the raw materials that could lead to a bomb, according to Trump's envoy, Steve Witkoff.

The two sides remain divided on the key question of whether Tehran will be allowed to enrich its own uranium as they meet for their fourth round of negotiations on Sunday.

A fourth round of talks between the US and Iran on Iran’s nuclear program have begun in Oman, according to Iranian state media, with the two sides aiming to overcome divisions that could scupper the tentative negotiations.
