In January 2016, a fresh wave of militancy and insecurity struck the Niger Delta region, MANA correspondent reported.
Throughout the year, Nigerian pirate groups stopped hijacking tankers for product theft and have started to kidnap crew for ransom.
At least 52 Nigerian pirate attacks occurred in 2016, EOS Risk Group said.
The majority of attacks off Nigeria in 2016 involved oil/chemical tankers, followed by offshore support vessels. Bulk carriers, containerships, general cargo vessels, LNG tankers, fishing vessels, a refrigerated cargo vessel, a dredger and a vehicle carrier were also subjected to attacks during the year, according to the group.
