A large explosion at Shahid Rajaei port in southern Iran killed 25 people and injured 800, according to Iranian state media. Private security firm Ambrey said that the port had received a shipment of ammonium perchlorate, a missile propellant ingredient, from China in March and that initial reporting indicated the explosion was linked to improper handling of the chemical. The Iranian defense ministry denied that consignments with military applications were present at the port.
