At least 14 people have been killed and 750 injured in a huge explosion at the port of Bandar Abbas in southwestern Iran, according to official Iranian media citing the country’s interior ministry.
The explosion sent a huge plume of thick, gray smoke from the Shahid Rajaee part of the port complex, according to videos geolocated by CNN, with the government saying the blast was likely linked to chemicals being stored.
No cause has been given for the explosion. A government spokeswoman, Fatemeh Mohajerani, said it would take some time to establish the cause, “but so far what has been determined is that containers were stored in a corner of the port that likely contained chemicals which exploded.
