DUBAI, United Arab Emirates >> Iran’s president on Sunday visited those injured in a huge explosion that rocked one of the Islamic Republic’s main ports, a facility purportedly linked to an earlier delivery of a chemical ingredient used to make missile propellant.

The visit by President Masoud Pezeshkian came as the toll from Saturday’s blast at the Shahid Rajaei port outside of Bandar Abbas in southern Iran’s Hormozgan province rose to 40.

While Iran’s military sought to deny the delivery of ammonium perchlorate from China, new videos emerged showing an apocalyptic scene at the still-smoldering port. The burning smoke was so dangerous that authorities closed schools and businesses in the area.
