A Catholic priest is among 11 people facing charges after a young albino man was found buried with several body parts missing in Malawi.

The dismembered corpse of McDonald Masambuka, 22, was found buried in southern Malawi several weeks after he went missing in March.

He is the 22nd albino person to be murdered in the southern African nation in four years, sparking calls for their killers to be executed to deter further attacks.

Malawi is one of the most dangerous countries in the world for people with albinism, a lack of pigmentation in the skin, hair and eyes, because their body parts are used in magical potions and other ritual practices.

As well as a Catholic priest, a police and medical officer are among the 11 people facing charges of conspiracy and murder, police spokesman James Kadadzera said.

Information minister Nicholas Dausi said international rights groups and donors were preventing the government from using the death penalty to deter such crimes in Malawi, where people with albinism are hunted down for their body parts.

'They are stopping us from enforcing capital punishment,' Dausi was quoted by local media as saying at Masambuka's funeral last month. 'Yet in their countries they execute murderers. Is this fair?'

The United Nations' top expert on albinism has said people with the condition risk 'extinction' in Malawi due to relentless attacks fuelled by superstitions.

President Peter Mutharika has since said Malawi should have an 'honest debate' about whether to apply the death sentence to those found guilty of murdering people with albinism.

Malawi suspended capital punishment more than 20 years ago as it embraced democratic reforms.

Although the death penalty still exists in law, it has been declared unconstitutional.

But rights groups said the focus on the death penalty was misplaced and the government should step up its efforts to investigate unsolved murders and protect people with albinism.

'We never have any experience where the death penalty has been successful as a deterrent,' said Overstone Kondowe, head of the Association of People with Albinism in Malawi, which helps about 3,400 people with the condition.

It has recorded 146 attacks in Malawi since 2014. About one in 20,000 people worldwide have the congenital disorder, with higher rates in sub-Saharan Africa.

Only five of 22 murders reported since 2014 are in court, said Kondowe, with 17 unsolved.

'We don't have even have a suspect and nobody has been prosecuted,' he said of the 17 cases, adding that the police should reopen them now that they have better equipment.

'We didn't have facilities of DNA testing to help with the investigation, so we're seeking that because the current capacity can help to shed light on who was responsible.'

Rights groups called on the government to establish a commission of inquiry to find out who is behind the attacks, amid claims that they are organised by criminal gangs.

'There is a green light with the recent case where we have seen high profile people involved,' said Timothy Mtambo, who heads the Centre for Human Rights and Rehabilitation, a charity.

'We believe a good investigation can open up our windows as to who is behind the trade ... We would be able to say we have unveiled the market and done (away) with the roots.'

Mtambo also echoed a United Nations' call on the government to implement its own plan to strengthen protection measures, including buying sturdy locks for poor families at risk of attack, and for public education to eradicate superstitions.

'It should invest in preventative measures, not 'curing' the problem,' he said. 'It needs to understand where we have people with albinism, which can help in drawing security plans. Currently there is no proper programme.'
