A massive explosion and fire at Shahid Rajaei port in Iran has resulted in at least 18 deaths and nearly 800 injuries. The blast is believed to be linked to a shipment of ammonium perchlorate, a chemical used in missile propellant, that was received from China. The cause of the explosion has not been confirmed, but social media footage suggests it may have been triggered by a chemical compound. While no official allegations have been made, the incident raises suspicions of potential outside interference due to Iran's tense relationship with Israel. The blast has also raised concerns about environmental damage and public safety.
