New images have been released of the Royal Navy's HMS Trent off the coast of West Africa.
The photos include Royal Marines from 42 Commando and sailors on board the ship conducting a boarding exercise with Nigerian Forces as part of an anti-piracy exercise.
Nigerian Forces boarded HMS Trent, clearing all areas of a potential threat before receiving specialist boarding and medical training.
The River-class patrol ship left Gibraltar for the waters of the Gulf of Guinea in October and will continue to support Maritime Security in West Africa during her time there.
HMS Trent is the first Navy vessel to operate in the region for three years and will help partner nations to develop key maritime skills and develop plans for future operations in the region, the Ministry of Defence said.
The ship is expected to visit Nigeria, Ghana, Senegal, Gambia and Cape Verde and take part in French-led multinational training exercises – bringing together international partners in the region.
