Two British nationals who were held hostage in the Democratic Republic of Congo (DRC) have been released, British Foreign Secretary Boris Johnson said on Sunday.
A park ranger was killed during the kidnapping, which took place near the village of Kibati just north of Goma.
The Britons were among three people abducted by unidentified armed men while reportedly visiting Virunga National Park, a renowned gorilla sanctuary in the east of the country.
A spokesperson for the Congolese Institute for Nature Conservation (ICCN) said: "For the moment the [ICCN] can not communicate much about the incident because the hostages are still in captivity".
Two Britons held hostage in the Democratic Republic of Congo have been released unharmed.
The two British tourists were kidnapped last week at a national park which is well known for its rare mountain gorillas in the central African country.

Park Director Emmanuel de Merode said she showed "true bravery" in her work.
"We wish to extend our sincerest condolences to her family, and our thoughts are with all those affected by this incident".
Covering some 7,800 square kilometers (3,011 miles), the Virunga national park is one of the most important conservation sites in the world. Virunga Park is home to about one-quarter of the world's remaining mountain gorillas, and the work of protecting them has proven risky.
Following Friday's kidnapping, the British Foreign Office "advised against all but essential travel" to the DRC province where Virunga park is located.
Before taking the tourists, they murdered the park ranger, Rachel Katumwa, 25, who had accompanied them there.
Rising violence in recent months across the province of North Kivu has been linked to broader political instability in DR Congo.
Last month, five young rangers and a driver were killed in a militia ambush, the park said.
