US President Donald Trump warned Iran yesterday that Iran would "sting" Iran "as never before," after Iranian President Hassan Rowhani said that "his country will enrich uranium to the ceiling set by the nuclear agreement In 2015, "while the US Senate called on Trump to act against Tehran's nuclear violations.

In detail, Trump said in a tweet on Twitter: "Iran has just issued a new warning. Rohani says they will enrich uranium (if any), if there is no new nuclear agreement. " "Be aware of the threats," he said. "They can bounce back to bite you and no one ever bites."

The Iranian president, Hassan Rowhani, said yesterday that his country will raise the rate of uranium enrichment more than 3.67%, after four days. He also explained that if the countries that are still within the nuclear agreement did not fulfill their promises, the reactor will return after the seventh of July for its previous activities. "Iran will remain committed to the nuclear agreement, as long as the other side is committed," he said.

Three days after Iran ends the European Union to breach the two most important items in the nuclear deal, the return to enrich uranium and heavy water at high rates, if European countries did not activate the channel of trade and banking exchange with Tehran by the seventh of July.

Iranian Foreign Minister Mohammad Javad Zarif admitted Monday that his country's stockpile of enriched uranium had exceeded 300 kilograms, and Iran had threatened to do so.

The EU has urged Iran to abide by the terms of the deal, but Tehran says its commitment to it will gradually decline until Britain, France and Germany promise to return materially, which was the main incentive for signing it.

In the same vein, three members of the US Senate, Marco Rubio, Ted Cruz and Tom Cotton, demanded the night before in a letter directly to President Trump to move against Iran's nuclear violations.

The letter came after the International Atomic Energy Agency (IAEA) confirmed that Iran was violating restrictions on the storage of low-enriched uranium in accordance with the Joint Comprehensive Action Plan for the Nuclear Agreement (JCPOA).

The three Republican members called on Trump to confront Iran's violation by increasing pressure on Iran's nuclear program, specifically ending civilian nuclear exemptions issued by the State Department earlier.

They also called for action through UN Security Council Resolution 2231 (2015), which prohibits Iran from nuclear activities outside the agreement.

The signatories described it as "nuclear blackmail" and stated that Iranian regime officials intended to move towards nuclear weapons while demanding concessions.

The three Republican members of the US Senate said Trump had properly decided to withdraw from the deal, which gave Iran much, while imposing very few restrictions.

They added that the United States "no longer continues on a path whose expected outcome is more violence, more terrorism and a real threat."

They also praised Trump for restoring economic pressure properly on the Iranian regime to offset the catastrophic effects of the nuclear deal and pressuring them to negotiate a better deal.

These deputies believed that civilian nuclear exemptions should be abolished, including at the centrifuge center at the Fordo facility, allowing the production of heavy water related to plutonium, and the development of ballistic missiles.

They stressed that the abolition of the IAEA inspection and reporting authorities to find violations had motivated the remaining parties to the agreement to ignore Iranian violations and clandestine aspects, allowing Iran to retain more than what was specified.

They also said that the flow of hundreds of billions of dollars into Iran allowed Iranian leaders to strengthen their military and terrorist activities at the regional and global levels, while maintaining a nuclear weapons infrastructure and periodically bypassing nuclear material restrictions.

In May, Washington ordered all states to stop buying Iranian oil, or face sanctions. Additional forces were sent to the area to counter Iranian threats.

On the other hand, a spokesman for the Supreme National Security Council of Iran, yesterday, the confirmation that Iran will begin next Sunday in the implementation of the next step to reduce its nuclear commitments.

"On July 7, the second step will begin to reduce the obligations of the nuclear agreement, according to paragraphs 26 and 36, according to what the Islamic Republic sees," the official IRNA news agency quoted spokesman Kiwan Khosravi as saying.

For his part, the Iranian Minister of Internal Security Mahmoud Alawi, yesterday, two conditions for talks between Tehran and Washington, the lifting of US sanctions and the approval of Iranian guide Ali Khamenei, as quoted by the agency «Islamic Republic».

"Iran could reconsider talks with the United States, but in the case of Trump's lifting of sanctions and the approval of our Supreme Leader for such talks," he said.

He said that the Americans were "terrified of Iran's military power", which led them to cancel the attack on Iran.
