Officials fear an oil tanker that caught fire after colliding with another ship off the coast of China could explode.
According to several reports, thick smoke and fierce heat billowing from the Iranian oil tanker are hampering attempts to rescue the 32 people who were on board.
Authorities say all 21 crew members on the other ship were saved. But the tanker wasn't as lucky. Its entire crew was missing after the collision. At least one body has reportedly been recovered.
It's still unclear exactly what caused Saturday's collision.
