TEHRAN:  (AP) A massive explosion and fire rocked a port on Saturday in southern Iran, injuring at least 516 people, state television reported.

The blast happened at the Shahid Rajaei port just outside of Bandar Abbas, a major facility for container shipments for the Islamic Republic that handles some 80 million tons (72.5 million metric tons) of goods a year.

Social media videos showed black billowing smoke after the blast. Others showed glass blown out of buildings kilometers away from the epicentre of the explosion.
