A 90-year-old archbishop was briefly abducted in a western Cameroon region gripped by conflict between anglophone separatists and security forces, the archdiocese said on Friday.
Christian Tumi, an archbishop emeritus and retired cardinal who has frequently sought to mediate in the crisis, was kidnapped on Thursday evening on a road near Kumbo in the Northwest Region, it said.
He was released on Friday along with his driver, said Samuel Kleda, archbishop of the port city of Douala.
But around 10 other people who were also seized with them have not been freed, a local official who requested anonymity told AFP.
Among those travelling with Tumi was a local leader, Sehm Mbinglo, the traditional chief of Nso, the official said.
Local people are negotiating for their release, the source said.
Kleda told AFP, "The cardinal and his driver were released a short time ago. It's a relief, but it is also terrible to know that a 90-year-old cardinal was taken hostage."
More than 3,000 people have been killed and more than 700,000 have fled their homes since October 2017, when militants declared independence in two western regions where English speakers are a majority. The declaration has not been recognised internationally.
Rights groups say crimes and abuses have been committed by both separatists and security forces.
The separatists frequently carry out kidnappings, often for ransom, although there have also been killings of abducted security personnel, teachers and civilians accused of collaborating with the authorities.
On Tuesday, separatists kidnapped 11 teachers in a raid on a Presbyterian school in Kumbo but freed them two days later after local people went to their camp and called for their release, according to Samuel Fonki, head of the Presbyterian Church of Cameroon.
On October 24, seven children were killed in a school in the Southwest Region, which the government has blamed on militants.
Anglophones in Cameroon have nursed decades-long resentment at perceived discrimination at the hands of the francophone majority.
Demands by moderates for reform and greater autonomy were rejected by the central government, fuelling momentum for the declaration of independence in 2017.
English speakers account for about four million of Cameroon's 23 million population.
Their presence is a legacy of decolonisation some 60 years ago.
In 1961, a British-ruled territory, the Southern Cameroons, voted to join the newly independent former French colony of Cameroon. The Northern Cameroons joined Nigeria.
