The death toll from a major explosion in Iran's most important container port of Bandar Abbas rose to at least 70, with over 1,200 injured, state media said on Monday, as firefighters battled a blaze that Iranian officials said was now under control 48 hours after the start of the fire.

A massive explosion rocked a port in southern Iran believed to be linked to a shipment of a chemical ingredient used to make missile propellant, as the U.S. and Iran held a third round of nuclear talks.
