Iran launched its eleventh wave of missile strikes overnight, claiming to deploy Fattah hypersonic missiles against Israeli targets. State media reported 1,800 Israeli casualties, though verification remains impossible. Israeli forces confirmed striking Iranian centrifuge production facilities and the Revolutionary Guard's Imam Hussein Officers University in Tehran.
Supreme Leader Khamenei broke his public silence with a televised address warning that any US military intervention would result in "irreparable harm." This marked his first public appearance since Friday's Israeli strikes. Trump remained publicly undecided about joining the conflict.
The diplomatic narrative shifted dramatically when Trump claimed Iran had requested White House negotiations, which Iranian officials categorically denied. Iran launched a twelfth wave using heavy Sejjil missiles while experiencing what outlets described as near-complete internet disruption and cyberattacks on banking systems. European foreign ministers scheduled emergency talks with their Iranian counterpart in Geneva, as the UN Security Council convened at Iran's request.
