Iranian Foreign Minister said that due to the talks held between Tehran and Washington, civilians can't make any transactions.

Tehran, Iran - Iran emphasized its right to enrich uranium for civilian purposes, as the Iranian delegation led by the Foreign Minister reached Muscat, the capital of Oman, and held a fourth round of indirect nuclear negotiations with the United States.

Foreign Minister Abbas Araghchi told state media on Sunday that the Iranian state has the legal right to enrich the rights of civilians who cannot trade in any way.

U.S. President Donald Trump withdrew the landmark 2015 Iran nuclear deal in his first term, allowing Iran to engage in civilian nuclear activities but limit enrichment to prevent Tehran from building nuclear bombs.

“Abundance is one of the achievements and honors of the Iranian country. We have paid a heavy price for abundance. The blood of our nuclear scientists has spilled over for this achievement. Israeli assassination scientist over the years.

But Aragic said Tehran is still committed to providing verifiable assurance that it will not be able to develop nuclear bombs - a major need for Trump.

Araghchi visited Saudi Arabia and Qatar and met with senior officials to coordinate the latest nuclear negotiations.

In the Oman capital on Sunday, Iran's top diplomats accompanied his representatives and other team members to mediate "indirectly" and "indirectly" technical negotiations emphasized by Iran through Oman.

Tehran has also repeatedly expressed concern about the "contradictory" remarks of the US negotiators in the media, led by Trump's long-time friend and special envoy Steve Witkoff.

Under the auspices of Sunday's Muscat talks, Witkov once again called for a complete "demolition" of Iran's nuclear program, including the main locations in Natanz, Fodo and Isfahan. U.S. Secretary of State Marco Rubio and other senior officials suggested Iran must import rich uranium.

The fourth round of negotiations is scheduled to be held in early May, but must be postponed on "logistical reasons".

Delays occurred after the United States did not confirm its involvement and a series of fires occurred in several cities in Iran, including a series of cities caused by the explosion in the port city of Bandar Abbas, killing dozens of people and injuring more than 1,200 people.

Trump reportedly fired Mike Waltz, national security adviser to the Iran Hawk, this month after Waltz coordinated with Israeli Prime Minister Benjamin Netanyahu and advocated a war with Iran.

Trump, his team and Israel have repeatedly threatened to launch a devastating military strike that would not yield any results if negotiations soon.

Meanwhile, the U.S. blacklisted the Chinese Chemical Group and three port terminal operators on Thursday to try to target Iranian oil exports.

Driven by its "maximum pressure" on Iran, the United States has also promised to drive Iranian oil exports to "zero", although Tehran continues to ship oil to China despite sanctions.

Trump began a sanctions campaign after unilaterally breaching a 2015 nuclear deal with world powers that impose verifiable and strict restrictions on Iran's nuclear capabilities in exchange for sanctions on the country.

The agreement uses first-generation centrifuges to limit uranium enrichment to 3.67% in limited locations, but Trump claims that makes it "the worst deal ever" but it has time limits and sunset clauses.

Iran is currently enriching up to 60% of its nuclear weapons, which is close to more than 90% of what is needed to build a nuclear bomb, but the International Atomic Energy Agency said Tehran has not put in the effort to produce weapons.
