Iran Update Special Report, April 6, 2026

(Institute for the Study of War) Iran rejected a ceasefire agreement with the United States to pause the war and “reopen” the Strait of Hormuz on April 6. Iran’s rejection of the latest ceasefire proposal reduces the likelihood that the United States and Iran will reach an agreement by US President Donald Trump’s April 7 deadline. Trump has maintained his threat to strike Iranian energy infrastructure and bridges if Iran does not agree to a deal by April 7. Iran, Hezbollah, and the Houthis appear to have coordinated an attack targeting Israel on April 6, possibly to try to maximize the psychological effects of Iran’s limited ability to conduct large-scale attacks against Israel. The timing of these attacks suggests that the attacks were coordinated to some degree, given the vastly different travel times of the munitions fired at Israel by Hezbollah, Iran, and the Houthis. The Israel Defense Forces (IDF) confirmed on April 6 that it has struck Iran’s two largest petrochemical facilities in the past week that account for 85 percent of Iranian petrochemical exports. The IDF reported that the South Pars Complex contained infrastructure to produce explosives and propellant for ballistic missiles. – Iran Update Special Report, April 6, 2026 | ISW
