A container ship carrying chemicals has been on fire off the coast of Sri Lanka for six days.

The Singapore-flagged MV X-Press Pearl - carrying 1,486 containers, including 25 tons of nitric acid - was waiting to enter a port in Colombo when it caught fire on May 18, the Associated Press reported.

Sri Lanka's navy believes the fire was caused by chemicals being transported on the ship, which was loaded in Hazira, India, on May 15.

X-Press Feeders, which owns and operates the ship, said its 25 crew members have been taken to safety..

Sri Lankan Navy spokesman Indika de Silva told the Associated Press that firefighters on tugboats and a naval ship are all trying to douse the fire.
