From NATO CIMIC's offering:
Lloyd’s List reports that on 23 March, the Liberia-flagged chemical and oil tanker Zouzou was hijacked in the Gulf of Guinea by approximately 12 armed pirates. The pirates used a mothership and skiffs for the attack, which is a new tactic that is usually used by Somali pirates. The attackers have since left the vessel, after stealing some items from the ship, leaving the tanker’s crew unharmed.

This Day, a Nigerian news source, reports that, within the past two
months, 22 armed attacks were carried out on ships in the Bight of Benin.
Last year the region reported 58 pirate attacks...

According to IMBs Piracy reporting Centre (PRC) a chemical tanker was attacked by armed pirates on 22 March about 100 nm off Bonny Island, Nigeria. The master triggered the Ship Security Alert System (SSAS) and the crew retreated to the citadel. A nearby US warship responded to the alert. The pirates aborted the attack and the tanker’s crew is safe.

Slightly puzzled that a US warship was in the vicinity, just like a French warship in Stan's post. The wonders of navigation in such waters.
