The Danish military stated that the frigate Esbern Snare found the suspected pirate ship near several merchant ships.
The Danish Armed Forces said that a Danish naval patrol killed four pirates in an exchange of fire in the Gulf of Guinea off the coast of Nigeria.
“No Danish soldier was injured, but five pirates were shot dead,” the military said on Thursday.
“Four pirates died. One of them was injured,” it added.
A spokesperson said that the incident occurred outside Nigeria’s territorial waters.
The incident occurred on Wednesday when the frigate Esbern Snare, which had been patrolling the area since early November, tried to board the pirate ship.
The Danish army fired warning shots, and the pirates immediately responded.
The statement said: “The Danish soldiers took self-defense actions and retaliated.”
The spokesman said that this is the first time the frigate has fired during its current mission in the Gulf of Guinea.
The military said that the remaining four pirates were taken to the frigate. After the shooting, the pirate ship sank.
The Gulf of Guinea is a pirate hot spot stretching 5,700 kilometers (3,540 miles) from Senegal to Angola, with 195 attacks in 2020.
According to the International Maritime Office, in the same year, there were 135 hostage-taking incidents at sea in the area, 130 of which occurred in the area.
The Danish Defence Minister Trin Bramson told news agency Ritzau that the helicopter-equipped Danish frigate and its 175 crew are “completed an important task by protecting Danish and other merchant ships in the area.”
Copenhagen announced in March that it would send this ship to patrol the area, and about 40 Danish ships operate here every day.
Danish Prime Minister Met Frederickson and the main opposition MP Jacob Ellerman both plan to visit the frigate during their visit to Ghana on Wednesday and Thursday.
The Danish tabloid Ekstra Bladet reported on Thursday that they were not on the frigate at the time of the incident.
The frigate will operate in the Gulf region until April next year.
