Talks with Iran about his nuclear program held today in Oman were positive and productive, a senior US government official said, adding that the two sides have agreed to meet again in Europe “soon”.

“There are still a lot to do, but further progress has been made to reach an agreement,” the official added.

The United States and Iran today completed a third round of critical negotiations on the Iranian nuclear program in Oman, after several hours of “serious” discussions as Tehran called them, and is expected to meet again next week for new talks.

These indirect discussions held at a high level between the two countries, which have been enemies for four decades, are intended to reach a new agreement that will prevent Iran from gaining an atomic weapon-Philosophesis that Tehran denies it-in return for its first US. Donald Trump, from the international agreement that had been concluded three years earlier in Vienna.

The last round in Muscat allowed “all the basic principles, goals and technical concerns,” said Oman Badr al -Busayi, who has a mediator role.

The talks will continue with a new high -level meeting projected to take place on May 3, he added.

According to Iranian state television, diplomat chief Abbas Arakzi and American Special Envoy Steve Whitkov will return with their teams “in their capital for consultations”.

Iranian diplomacy spokesman Email Bagai spoke earlier about a “serious atmosphere” and said the discussions were held in “separate rooms”, as well as at previous meetings on April 12 in Muscat and April 19.

A member of the Iranian negotiating team told the local Tsinam agency that discussions were limited to sanctions and nuclear program.

“Differences” remain with the United States, the head of Iranian diplomacy said.

Western countries, led by the US, and Israel suspect that Iran wants to acquire a nuclear weapon. Tehran rejects these allegations, defending the right to nuclear energy for non -military purposes.

Thus, Arachi said on Tuesday that his country envisaged to build 19 new reactors.

In retaliation for US departure from the Vienna Agreement, Iran has distanced the text, mainly enriching heaven at a high level.

After returning to the White House, Donald Trump reiterated his so -called “maximum pressure” policy in Iran, inviting March to negotiate while threatening to bomb it in the event of diplomacy failure.

In statements published yesterday, Friday, at Time Magazine, he said he was ready to meet the country’s leaders.

At the same time, Washington announced on Tuesday new sanctions aimed at the Iranian oil sector, with Tehran denouncing a “hostile approach”.

On Wednesday, the International Atomic Energy Organization, which is in charge of supervising the Iranian nuclear program, asked Tehran to explain the presence of tunnels around Natanz (Central Iran) facilities that houses centrifugal devices used.

The Washington -based International Security Organization has released satellite images of this facility, showing a new tunnel and a more older tunnel and a new safety perimeter. Tehran has not reacted for the time being.

Iran is currently enriched heaven to a high grade (60%), below the 90% required to build an atomic weapon, but far above the 3.67% limit set by the Vienna Agreement.

According to Arachi, Iran’s right to enrich heaven “is not negotiable”.

On Thursday, he said he was willing to go to Germany, France and Britain, other countries that are members of the Vienna Agreement.

Last week, US Secretary of State Marco Rubio called on Europeans to quickly decide on UN sanctions to reinstate Iran. The 2015 agreement enables them to be automatically restored in the event of non -compliance, but this option expires in October.

Iran has warned that it could be withdrawn from the nuclear non -spread agreement if this mechanism is put on motion.
