tanker

Liberian oil tanker carrying Iranian crude oil exploded, causing a three-day fire that ended with a sunken ship. Two tug boats and a plane attempted to extinguish the fire. Seven vessels rescued the crew (27), but one crew member was killed and four were reported missing (died).

Clean-up Efforts 

None, as it was expected that the high seas would break up the oil and there would be no environmental impact.

Impacts 

An 80-square-mile slick surrounded the tanker, but it is not known how much oil sank or burned.
