reports that in recent months, there has been an increase in pirate attacks on cargo ships off the West African Gulf of Guinea. The region is second only to the coast of Somalia in the incidence of piracy.
The International Maritime Bureau says there have been 17 reported cases of pirate attacks in the first six months of this year in Nigeria's coastal waters.
reports that the pirate gangs operating off the Nigerian coast are mostly offshoots of militant groups that embraced the Nigerian government's amnesty program under the late President Umaru Musa Yar' Adua, in 2009.

This is not the first time pirates have attacked a vessel that belongs to Bourborn off the coast of Nigeria. Pirates kidnapped three French crewmen from a Bourborn-owned ship in a Nigerian offshore oilfield in 2010. But the men were released soon after.
Recently, pirates also attacked a Greek-owned ship with a crew of over 20 off the coast of Togo, West Africa. They stole 3,000 tonnes of fuel but released the crew and ship.
