A senior Iranian parliamentary official warned on Tuesday that enriching uranium to 90% purity, the weapons-grade threshold, is "one of Iran's options" if the country came under attack again.
Ebrahim Rezaei, spokesman for Iran’s parliament’s Foreign Policy and National Security Committee, posted to X: "One of Iran's options in the event of another attack could be 90% enrichment. We will examine it in parliament."
Uranium enriched to 90% purity is the level required for nuclear weapons.
The statement came as Iran's foreign ministry spokesman Esmail Baghaei, in his Monday press briefing, reiterated that Tehran's nuclear file would not be discussed until the war ended on all fronts, and described Iran's peace proposal as "generous and responsible."
Pakistani government sources familiar with the mediation process told Türkiye's state-run Anadolu Agency (AA) that Iran's response to the U.S. proposal focused overwhelmingly on an "immediate" end to the war and offered "little in terms of Washington's core demand about Iran's nuclear program."
However, the sources disclosed details not confirmed by either side publicly: Tehran had reiterated its willingness to halt uranium enrichment for five years, while rejecting Washington's demand for a 20-year moratorium. It had also rejected U.S. demands for dismantling the underground nuclear facilities, insisting that it has no plans to develop nuclear weapons.
Iran proposed "broader and separate" talks on the nuclear file, considering its "complexity," and suggested nuclear talks begin within a month of a war-ending agreement.
Tehran also reiterated its readiness to reopen the Strait of Hormuz in exchange for an end to the U.S. naval blockade of its ports, and repeated demands for billions in frozen assets, war damage compensation and sanctions relief.
"Back-channel contacts are continuing despite harsh tones from both sides, with several regional countries including Qatar and Egypt assisting Islamabad in its mediatory efforts," one Pakistani source told AA.
Pakistan "does not see any immediate danger vis-a-vis resumption of war," partly because President Trump does not want the resumption of hostilities to overshadow his upcoming Beijing visit, the sources said.
In a pre-recorded interview with journalist Sharyl Attkisson, Trump said the U.S. had Iran's nuclear materials site "very well surveilled" and threatened military action against anyone who tried to access it.
"If somebody walked in, they can tell you his name, his address, the number of his badge," he said, citing the U.S. Space Force's surveillance capabilities.
"If anybody got near the place, we will know about it and we'll blow them up," he added.
Trump claimed the U.S. had struck "probably 70%" of the targets it had intended to hit in Iran and said reconstruction would take two decades.
"We cannot let Iran have a nuclear weapon because they're crazy," he said.
On Truth Social, Trump accused Iran of "playing games" with the United States for 47 years and condemned what he described as Iranian actions during the Obama and Biden administrations, warning: "They will be laughing no longer."
Israeli Prime Minister Benjamin Netanyahu, in his CBS News interview, reiterated that the war is "not over" until Iran's enriched uranium is physically removed and enrichment sites dismantled, telling CBS that Trump had told him personally, "I want to go in there."
Netanyahu declined to discuss military timetables or means.
Israeli media separately reported Trump had assured Netanyahu he would not make concessions on the uranium stockpile.
