Voting is under way in a controversial by-election in the north-west Ugandan town of Arua.

Dozens of people were arrested ahead of the vote, including the main opposition candidate and one of his key supporters - the popular Afrobeats musician and MP Robert Kyagulanyi, known as Bobi Wine.

They were arrested after a vehicle in President Yoweri Museveni's convoy was attacked late on Monday.

Wine’s driver was later shot dead.

The by-election is taking place because the previous MP for Arua, Ibrahim Abiriga, was shot dead in June in still unexplained circumstances.

So far there are reports of a low voter turnout in Arua, which is a regional hub close to Uganda’s borders with South Sudan and the Democratic Republic of Congo.

The opposition in Uganda has long accused President Museveni of using the military and police to influence the outcome of elections. He denies the allegation.

Many Nigerians have welcomed the news that Nigeria's notorious anti-robbery squad, known as Sars, is to have a makeover.

They responded to the presidential statement released on Twitter, external where a sustained #EndSars campaign has been running. This tweet shows a victorious Fela Kuti - Nigeria's legendary musician, who was never scared of taking on authority.

Yemi Osinbajo, who is acting president while Muhammadu Buhari is on holiday, comes in for much praise for his decision:

The leader of the #EndSars movement, Segun Awosanya, has also been credited for his hard work to highlight the alleged abuses committed by the squad:

Zimbabwe’s ruling party, Zanu-P,F has filed papers opposing the MDC Alliance’s challenge to the presidential election result, the state-run newspaper, the Herald, says, external.

Official results show that President Emmerson Mnangagwa won 50.8% of the vote compared to opposition MDC Alliance leader Neslon Chamisa's 44.3%.

The MDC Alliance says the poll was marred by "mammoth theft and fraud", but the electoral commission insists that there was "no skulduggery".

Zanu-PF's lawyers say the MDC Alliance challenge came too late as their papers were filed on Friday afternoon.

“We will show the court that Chamisa’s lawyers had until Friday 10 am [08:00 GMT] to file and serve their papers,” Zanu-PF lawyer Lewis Uriri is quoted by the Herald as saying.

Mr Mnangagwa has been hoping these elections would legitimise his rule after taking over amid a military intervention that saw Robert Mugabe resign in November as president after 37 years in power.

Nigeria's Acting President Yemi Osinbajo has ordered the immediate overhaul of a police unit following allegations of human rights abuses.

The special anti-robbery squad, known as Sars, will be reformed and a new commissioner appointed to head it.

The unit has become notorious for allegations of extra-judicial killings, arbitrary arrests, torture and extortion.

There has been growing public pressure for the squad - responsible for tackling serious crime such as armed robbery, kidnapping and cattle rustling - to be disbanded.

The hashtag #EndSars has been trending in Nigeria for months.

In a statement Mr Osinbajo, external, who is the country’s vice-president, said he was taking this action “following persistent complaints and reports on the activities of the Special Anti-Robbery Squad (Sars) that border on allegations of human rights violations”.

The vice-president is filling in for President Muhammadu Buhari who is currently on holiday.

He said the reformed unit should be intelligence-driven and its mandate restricted to combating armed robbery and kidnappings.

Members of the squad should wear proper identification while on duty as well as respect human rights and the rule of law, he added.

The National Human Rights Commission of Nigeria has also been directed to set up a special panel to investigate the alleged unlawful activities of the anti-robbery police unit

The committee is to give the public the opportunity to present their complaints and seek redress.

Mauritius’ former President Ameenah Gurib-Fakim, who resigned in March over an expenses scandal, has appeared in front of a government inquiry for questioning.

Ms Gurib-Fakim denies any misconduct amid claims that she made large personal purchases on a charity bank card.

She told the inquiry that, when in office, she had set up an inquiry into the activities of Angolan businessman Álvaro Sobrinho because she felt under pressure.

Before her resignation, the Mauritian daily L'Express published bank documents purporting to show Ms Gurib-Fakim had used a credit card given to her by the Planet Earth Institute (PEI) in London to buy thousands of dollars’ worth of clothes, jewellery and other personal items.

According to the paper, the card was given to her as part of her work as an unpaid director for the charity.

One of the organisation's directors is Álvaro Sobrinho who, the paper says, secured a permit to found an investment bank in Mauritius, prompting allegations of favouritism.

The inquiry that Ms Gurib-Fakim launched earlier this year was roundly criticised at the time by the government, who said it was not within her powers to do so.

She defended that decision today, saying "there was a sense of isolation, total lack of support from the executive…There was no will whatsoever to help the office of the president".

"The Attorney General told me that he could not do anything while the office of the presidency was under attack."

She also told the inquiry she had been advised not to speak to the press.

The inquiry is expected to continue for a number of days.

The head of the World Health Organisation (WHO), Dr Tedros Adhanom Ghebreyesus, said his visit to the Democratic Republic of Congo has made him even more worried about the outbreak.

Ongoing conflict makes it more conducive for the virus to spread and there are difficulties accessing areas affected, the director general said at a press conference in Geneva on Tuesday.

One of the particularities of this outbreak, Dr Tedros said, is that there are more women and children affected than in previous outbreaks.

Seven health workers have also tested positive. Because of that, all 74 health workers at one of the main hospitals have been put on temporary leave.

So far, nearly 200 health workers and 20 community members have been vaccinated. Today, an experimental treatment developed in the US was also deployed.

DR Congo is facing its 10th Ebola outbreak. There are 30 confirmed cases reported and 41 people have died in the eastern provinces of North Kivu and Ituri.

The root cause of this latest outbreak is still unknown.

The musician-turned-opposition MP Robert Kyagulanyi, better known as Bobi Wine, and three other lawmakers are in police custody.

Paul Mwiru, Gerald Karuhanga, Francis Zaake and Mr Kyagulanyi, were arrested following violence at a campaign rally attended by President Yoweri Museveni - whose car was pelted with stones according to authorities.

Former MPs Kasiano Wadri and Michaal Mabikke are also among those detained.

In a statement, police spokesperson Emilian Kayima said they intervened "to contain the situation", using "teargas and shooting" to prevent an escalation.

The detained MPs are accused of blocking the president convoy and attacking it, according Mr Kayima.

He also confirmed that Mr Kyagulanyi's driver had died from a gunshot wound, but did not state who the culprit was.

The BBC's Ed Butler speaks to one man in Uganda who says a powerful gang has attacked and tried to kill him in order to claim his ancestral land.

The police officer accused has yet to be tried and is still working, contrary to police guidelines.

Land disputes are common in Uganda, according to local media reports.

There are calls for the Ethiopian marathon runner famous for his pro-Oromo protest at the Rio Olympics to return home, reports the government-affiliated Fana Broadcasting Corporation.

“Both the Ethiopian Olympic Committee (EOC) and Ethiopian Athletics Federation (EAF) have called athlete Feyisa Lilesa to return home. He will be given a hero's welcome”, the broadcaster said in a tweet.

Feyisa refused to return home after the 2016 Rio Games, saying his life would be in danger.

As he took the silver medal, Feyisa crossed his arms above his head - a gesture made by the Oromo people who had been suffering brutal police crackdowns.

Feyisa now lives in the US with his family.

Cameroon's government has announced the arrest of six soldiers following a probe into a video released a few weeks ago that documented the abuse of civilians, the privately-owned Cameroon Info news site reports.

It marks a U-turn from their previous denials that any arrests had been made over the video which emerged last month.

The six soldiers are suspected of being the perpetrators of, or accomplices in the summary executions of women and children in the Far North Region, Cameroon Info reports.

In the clip which circulated widely on social media, men wearing military fatigues shoot two women, including one with a baby on her back, and a little girl.

They are heard accusing the victims of being connected to the Islamist militant group, Boko Haram.

The Cameroonian army is deployed in the country's Far North region to counter frequent incursions by Boko Haram fighters from Nigeria, where the jihadists are based.

Rights groups have accused the Cameroonian armed forces of carrying out war crimes in their fight against the militant group.

Two Ugandan journalists, who were arrested following Monday's violence, have been released on a police bond and are alleged to have been tortured by authorities.

Herbert Zziwa and Ronald Mwanga were "violently arrested by armed men in military fatigues while reporting live on air", their employer NTV Uganda said in a statement.

NTV Uganda says the journalists were taken to an unidentified location and "physically assaulted repeatedly".

Both men were charged with incitement of violence and malicious damage before being released on Tuesday.

NTV Uganda condemned their "torture and unjustified detention" and plans to "robustly defend them against these charges".

Police said on Monday opposition supporters pelted the convoy of President Yoweri Museveni with stones.

Security officers then intervened. The ensuing clashes killed the driver of musician-turned-opposition leader, Robert Kyagulanyi, popularly known as Bobi Wine.

Among those arrested were Ugandan opposition MPs, including Me Kyagulanyi, and dozens of other people.

Egypt's sports minister has announced that fans will be allowed back to watch league matches on a regular basis for the first time since 2012.

Supporters were banned from attending matches in February 2012 after at least 74 fans of Al Ahly died during a game with Al Masry in Port Said.

The ban will be lifted on 1 September but initially only a maximum of 5,000 fans will be allowed into stadia.

Since 2012 limited numbers of fans have been able to watch certain matches.

Those games have included some internationals and some involving clubs playing in continental competitions.

A gradual return was due to start in early 2015 but 22 Zamalek fans died in a stampede at one of the very first games led to the ban being re-imposed.

Sport minister Ashraf Sobhy met with the Egypt Football Association and club representatives last week to reach the agreement that is now expected to be given final approval by the ministry of the interior.

South African President Cyril Ramaphosa has appointed Silas Ramaite as acting chief prosecutor.

He replaces Shaun Abrahams, who left office after the country's top court ruled on Monday that he was not validly appointed and was a beneficiary of former President Jacob Zuma's abuse of power.

The presidency said in a statement that Mr Ramaphosa would appoint a permanent chief prosecutor within 90 days.

Mr Ramaite is the National Prosecution Authority's deputy national director responsible for administration and office for witness protection. He has held that role since 2003.

Brigadier Zakariya Maimalari was one of the first Africans ever to train at the British Royal Military Academy at Sandhurst in the UK.

"He wouldn't condone any sloppiness and he would tell it as it is," says his relative Haruna Yahaya Poloma, who pieced together the details of his life and character into a biography called The First Regular Combatant.

He shares the story with BBC Focus on Africa's Veronique Edwards:
