Hawaii molasses spill kills thousands of fish

A 1,400-tonne treacle spill off the coast of Hawaii has killed thousands of fish, prompting health officials to issue a shark warning to swimmers.

A leak - discovered in a pipeline used to load the syrup onto ships - created a sugary brown slick in Honolulu's harbour and a nearby lagoon.
