Pirates operating in the Gulf of Guinea have kidnapped a total of 13 people on two European-flagged ships in the last three days.
Four crew members on a Greek oil tanker were kidnapped after pirates boarded the boat off the coast of Togo on Monday morning, while eight people were kidnapped from a Norwegian cargo boat during a similar incident off the coast of neighbouring Benin on Saturday.
The four kidnapped crew on the Greek ship consist of two Philippine nationals, one Greek and one Georgian, the Togolese navy said.
