Iran says 'initial assessment' for explosion, fire, at Bandar Abbas port indicates mishandling of dangerous chemicals.

The death toll from a powerful explosion at Iran's biggest port has risen to at least 40, with more than 1,200 people injured, state media reported on Sunday.

An explosion occurred at Iran's Shahid Rajaee port, resulting in at least four fatalities and over 500 injuries. Israel has denied its involvement. But an investigation is underway.
