There are concerns over the possible environmental impact of an explosion on an oil production vessel off the coast of Nigeria.
It is still not clear how much oil has spilled into the sea, and the fate of its 10 crew members is also unknown.
The vessel can hold up to two million barrels of oil, but an industry source said there were about 50,000 barrels in storage when it exploded on Thursday morning.
Soon after, footage from the scene near Warri in the Niger Delta showed a huge cloud of dark smoke billowing from the Trinity Spirit which was on fire and partly submerged.
