Firefighters are still working to put out a fire that erupted on a Hoegh Autoliners car carrier off Jacksonville, Florida, almost 21 hours ago, according to emergency responders.

The fire broke out shortly before 1600 hours local time on Thursday after an explosion occurred on the seventh deck of the 4,900-ceu Hoegh Xiamen (built 2010).

The ship had taken on about 2,000 vehicles at Blount Island Marine Terminal shortly before the explosion.
