The coast off Nigeria is the “most dangerous in the world”, the International Maritime Bureau (IMB) has warned.

The London-­based organisation, which monitors global piracy, did not make this comment in recent days — although it might well have done.

The warning came 16 years ago and has been repeated in various forms many times since.

As recently as 2016, IMB director Pottengal ­Mukundan talked of “unacceptable violence” against ships and their crews off Nigeria.
