Iran has threatened to cross the nuclear red line and push uranium enrichment to weapons-grade levels if the United States launches another strike on its territory. The warning came as some aides of President Donald Trump said he is now more seriously considering a resumption of combat operations in Iran.

Ebrahim Rezaei, spokesperson for Iran’s parliamentary national security and foreign policy commission, said Tehran could enrich uranium up to 90 per cent purity, which is a level considered suitable for nuclear weapons.

"One of Iran's options in the event of another attack could be 90 percent enrichment. We will review it in the parliament," Rezaei wrote on X.
