Dutch operator ForestWave has said 12 crew have been seized from a general cargoship by Nigerian pirates.

It had earlier said that gunmen boarded the 10,600-dwt FWN Rapide (built 2005) on Saturday morning as it prepared to enter Port Harcourt, Nigeria.

Two seafarers have remained on board and are safe and unhurt. They have moved FWN Rapide to a safe position.
