Angola's main opposition Unita party has released a statement criticising Portuguese President Marcelo Rebelo de Sousa for prematurely congratulating Joao Lourenco for becoming president-elect.

The statement said that it was with “amazement and disappointment” they heard him congratulate Mr Lourenco, who is the presidential candidate for the ruling MPLA party.

Provisional results, announced by Angola’s electoral Commission, say the MPLA has over 60% of the vote.

But in the statement Unita complained that the results have not been collated properly yet and, by announcing the provisional results, the electoral commission committed a gross violation of the law.

Portuguese newspaper D Noticias, external adds that activist Nuno Dala sent an open letter to the Portuguese president to criticise him for congratulating Mr Lourenco for, what he says are “forged results”.

Priscillah Mabelane has been appointed as the new chief executive of BP Southern Africa, eNCA reports, external.

The South African news site adds that Ms Mabelane, a chartered accountant, is the "first woman in the history of the country’s oil industry to head a multi-national company".

Before joining BP in 2011 as chief financial officer (CFO), eNCA says Ms Mabelane held senior roles at Airports Company of South Africa (ACSA), international tax and assurance company Ernst & Young, and South African electricity supplier Eskom.

Ms Mabelane will take up her new post on 1 September.

News site eNCA quotes BP Southern Africa chairperson, Thandi Orleyn, as saying:

A court in Nigeria has seized $21m (£16m) from bank accounts linked to former oil minister Diezani Alison-Madueke, who is being pursued by the national anti-corruption agency, the AFP news agency and Premium Times, external reports.

The Economic and Financial Crimes Commission (EFCC), argued that the money in the bank accounts had been laundered with the help of oil officials, AFP adds.

The ruling comes after a judge ordered the seizure of property worth $22m linked to Ms Alison-Madueke.

She was Nigeria's oil minister from 2010 to 2015 and has been the subject of an international anti-corruption investigation.

Ms Alison-Madueke has previously denied involvement in corruption.

South African house DJ and producer Black Coffee, who recently made headlines when he became the first African host on Beats 1, has now been praised for opening up about his disability on social media.

His left arm was left paralysed after a car accident in 1990 and his personal experience of disability moved him to create the DJ Black Coffee Foundation which helps fund sound production training for disadvantaged students, external.

In a Facebook post last night, external, Black Coffee shared the above photo of himself wearing an arm brace "for the first time in years", adding:

Black Coffee told his followers "don't let anything pull you down," and "fight for the best version of yourself".

Many on social media have praised the musician for his candour:

Nigerian Oshi Agabi has unveiled a computer based not on silicon but on mice neurons at the TEDGlobal conference in Tanzania.

The system has been trained to recognise the smell of explosives and could be used to replace traditional airport security, he said.

Eventually the modem-sized device, dubbed Koniku Kore, could provide the brain for future robots.

Experts said that making such systems mass-market was challenging.

All of the big tech firms, from Google to Microsoft, are rushing to create artificial intelligence modelled on the human brain.

While computers are better than humans at complex mathematical equations, there are many cognitive functions where the brain is much better: training a computer to recognise smells would require colossal amounts of computational power and energy, for example.

Mr Agabi is attempting to reverse-engineer biology, which already accomplishes this function with a fraction of the power it would take a silicon-based processor.

"Biology is technology. Bio is tech," he says. "Our deep learning networks are all copying the brain."

Angola's election last week "marked an important step towards consolidation of democracy" according to African Union election observers.

They announced the conclusion on Friday in French and Portuguese but did not release the statement in English, external until today.

The AU observers did not use the term "free and fair" when describing the elections in the almost-3,000 word statement.

Instead they concentrate on improvements that have been made, saying that the body:

This is not the AU's final conclusion as the vote count is still under way, and they promise a "more comprehensive and final report in due course".

The official result is not due until at least the 6 September.

But the electoral commission has already published provisional results, external they say count for over 98% of the votes, which show the ruling MPLA have won by 61.05% and the biggest opposition party, Unita, got 26.72% of the vote.

We reported earlier that the validity of these results is being disputed by the opposition parties.

In their statement, the AU observers encourage "recourse to legally established mechanisms should there be any dispute arising from the outcome of the elections".

Graphic warning labels have appeared on cigarette packets in Senegal, and a 2014 law banning smoking in public places has been enforced since the weekend.

Slogans like "smoking causes a slow and painful death" and "smoking leads to impotence" are combined with shocking photos of people suffering from smoking-related illnesses.

Senegal's health minister says a recent government survey of young people's smoking habits prompted the changes:

Senegalese smokers’ reactions to the new packets are mixed.

Many people buy individual cigarettes for around $0.05 (£0.04) each, rather than whole packets, meaning they will not necessarily see the new packaging.

And the tobacco giants are fighting back with discreet, unbranded kiosks which appeal to smokers and defy authority.

People in Mandera county, north-east Kenya, are celebrating the wedding of 80-year-old Abdullahi Ibrahim to a 60-year-old woman, Kahija, reports the BBC's Ahmed Adan.

He says that whereas an old man marrying a young bride is not so unusual, this kind of union is rare.

Abdullahi said his children (one of them is pictured on the right below) were in favour of the marriage:

The South African school where pupils went on strike to demand the right to wear skinny pants has resumed normal lessons, the local education authority has said.

In a statement, the Gauteng education department blamed "two unruly learners" who coerced other students into making the protest:

The local authority said the school should not be distracted by "petty issues".

Kenya has introduced a ban on plastic bags with some very harsh penalties for those who contravene it.

Anyone found selling, manufacturing or carrying them could face fines of up to $38,000 or prison sentences of up to four years.

So why so draconian? The BBC's Abdinoor Aden took this photo of a place where people dump their rubbish which could explain the problem that the authorities are trying to tackle:

Traders are having to find alternatives.

"Instead of risking jail and hefty fine, I better look at my children by following the law,’’ said Nyambura Mwangi, a trader at Gikomba second-hand market.

‘’I have been in business for nearly 20 years and this is the first time I am using other bags."

"They are more expensive, but the law must be followed," she added.

Abdinoor also found boiled egg breakfast snacks, which are normally wrapped in plastic bags, are now being sold in paper:

But the ban has been a boon for packaging sellers.

Eric Mbuvi, whose trade in sacks has been slow in the past has registered high sales today:

Fear has gripped Shayamoya village in South Africa's KwaZulu-Natal province after the discovery of a decapitated body.

The family of Zanele Hlatshwayo, 25, who has been missing since July, believe she was a victim of a cannibalism ring that has so far led to the arrest of five men.

Her decomposing body was found after a man who claimed to be a traditional healer handed himself over to police last week and confessed that he was tired of eating human flesh.

Police officers had initially dismissed his statement, according to reports.

It is only after he produced a bloodied hand and foot as proof that he was immediately arrested. He led them to his rented home, where police found eight human ears in a cooking pot.

It is believed they were to be served to his customers, who were told they had magic properties and would convey money, power and protection.

Several other body parts were found stuffed in a suitcase.

Ms Hlatshwayo's family is yet to bury her. As I entered the Hlatshwayo homestead, I was greeted by a solemn hymn and the cries by the grieving family.

"We can only imagine how she begged for her life, she died an extremely painful death," said her elder sister Nozipho Ntelele as she wiped away tears.

Fashion-conscious teenagers in South Africa's capital, Pretoria, are demanding the right to wear skinny pants to school, saying their current uniform is "too big".

Pupils at Hoërskool Pretoria Wes are boycotting classes in the hope that the school will give into their wishes, but the school's governing body isn't impressed. Cape Talk, external quotes the head of the governing body:

The school is being a paid a visit today by the education authority from the provincial government, Eyewitness News, external reports.

They are intervening because they fear the incident could set a "wrong precedent".

But official Panyaza Lesufi adds that although he is "taken aback", it is still within pupils' rights to "approach the school governing body... If they indeed want skinny pants."
