US President Donald Trump said on Sunday that Iran has reached out to propose negotiations amid deadly protests in the country. He added that the US is considering "very strong" military action against Iran over the crackdown that reportedly killed hundreds. Trump told reporters aboard Air Force One, "They're starting to, it looks like." He said, "The military is looking at it, and we're looking at some very strong options. We'll make a determination." According to the Human Rights Activists News Agency, at least 538 people have died, including 490 protesters. Over 10,600 were arrested, but casualty numbers vary due to limited access during Iran’s internet blackout. The Iranian parliament speaker, Mohammad Baqer Qalibaf, warned Washington against any miscalculation, stating, "Let us be clear: in the case of an attack on Iran, the occupied territories as well as all US bases and ships will be our legitimate target." Trump has threatened to "rescue" protesters if Iran kills them and said on Truth Social, "Iran is looking at FREEDOM, perhaps like never before. The USA stands ready to help!!!" Meanwhile, Reza Pahlavi, son of Iran’s former shah, urged Iranian security forces and government employees to side with the people. Iran’s president, Masoud Pezeshkian, accused Iran’s enemies of escalating the unrest and urged a "national resistance march." Iranian authorities have arrested key protest members, and protesters or helpers may face charges of being "an enemy of God," punishable by death. Israeli officials are on high alert but silent to avoid giving Iran a foreign interference claim. Internet services were cut off on Thursday, enabling authorities to intensify their crackdown. Reports say security forces used live ammunition and imposed martial law in cities like Sari as protests demand political reform and government change.
