Uganda's opposition leader Kizza Besigye has been charged with treason, the country's Daily Monitor newspaper is reporting, external.

He was arrested ahead of President Yoweri Museveni's inauguration yesterday for a controversial fifth term in office.

The Forum for Democratic Change leader denounced Mr Museveni's victory in February's election as a "sham" and held his own mock swearing-in ceremony on Wednesday.

His wife told the BBC yesterday that she had no idea where the authorities had taken him after his arrest and she had heard a rumour that he'd been flown to the north-east of the country.

The Daily Monitor says that he is indeed in the north-eastern Karamoja region, remanded in custody at the Moroto government prison until 25 May for a court appearance.

Fatma Samoura’s appointment as Fifa’s first female secretary general (see 16:47 post) is significant in several ways .

Of the 209 football association presidents around the world, just two are women - while it was only four years ago that football’s world governing body appointed its first female executive.

This gives an indication of the enormity of this decision.

She is also an African - a continent that has never had an elected Fifa president.

Ms Samoura can now claim to have the most important job in world football because Fifa’s new reforms, which were implemented earlier this year, means that the president, Gianni Infantino, has less powers.

In football parlance, this is a major upset.

In our series of letters from African journalists, Joseph Warungu considers what the collapse of a building in Nairobi reveals about Kenyan society.  

More than 30 buildings have collapsed in the last 10 years in different parts of Kenya, killing and injuring people.    

He says impunity means you can put up an unsafe building in an unsafe area and stuff it with desperate families.

Some people on Facebook have reacted, external angrily to such harsh criticism:

While others defend the article:

The first Nollywood film starring a British actress speaking Pidgin is going on general release in cinemas across Nigeria today.

The actress Claire Edun posted a snippet from the film ATM on Instagram:

Mrs Edun became famous in Nigeria after posting on YouTube comedy rants in Pidgin, using the pseudonym "Oyinbo Princess". Oyinbo means white person in Pidgin.

The director of the romantic comedy, Lacelot Oduwa, told the BBC's Martin Patience that her language skills fill him with joy.

Rwandan President Paul Kagame has denied allegations by UN experts that his country is continuing to support rebels in neighbouring Burundi (see 09:40 post).

His Twitter feed said the problems in Burundi originated from within the country, not elsewhere:

Burundi has suffered a violent political crisis since President Pierre Nkurunziza decided to run for a controversial third term last year.

It is exactly a year since Mr Nkurunziza survived a coup attempt.

Rwanda denied similar allegations about supporting rebels made in a previous UN report in February.

The BBC's Great Lakes service has put together a gallery of Burundi's year of violence.

One construction workers has died after being injured when a four-storey shopping mall being built in a busy area of Abeokuta in Nigeria’s Ogun state collapsed (see 11:23 post).

Fifteen other workers believed to have been at the site were rescued; seven of them have been injured.

Rescue work is ongoing at the site in case hawkers who often go there to sell food are affected. Unconfirmed reports say 10 bystanders may have died.

Building collapses are not uncommon in Nigeria as sometimes builders try to cut corners by using inferior materials.

They often bribe corrupt officials so as to avoid complying with building regulations.

The European Union (EU) naval mission to tackle people smuggling in the central Mediterranean is failing to achieve its aims, a British parliamentary committee says.

In a report, external, the House of Lords EU Committee says Operation Sophia does not "in any meaningful way" disrupt smugglers' boats.

The destruction of wooden boats has forced the smugglers to use rubber dinghies, putting migrants at even greater risk, the document says.

The BBC's Christian Fraser has been tweeting from a charity vessel, the Aquarius, assisting Italian officials to rescue migrants.

Operation Sophia:

• Almost 14,000 migrants rescued since operation began (22 June 2015)
• 114 people smugglers' boats seized
• 69 suspected smugglers and traffickers arrested by Italian authorities
• Operation has five warships - Italian flagship Cavour, two German, one UK, one Spanish
• And seven aircraft (three helicopters, four planes)

Fatma Samoura from Senegal has been appointed to run Fifa, the body that governs world football.

For the last 21 years, Ms Samoura has worked for the United Nations.

Earlier this year, Fifa banned its former secretary-general Jerome Valcke from all football-related activity for 12 years.

Ms Samoura will be in charge of the day-to-day running of Fifa, which has had a troubled year amid corruption scandals.

Kenya’s Sports Minister Hassan Wario will be leading a delegation to Canada for urgent talks with the World Anti-Doping Agency (Wada) after it ruled that Kenya was in breach of global anti-doping rules.

He made the announcement after a lengthy meeting with President Uhuru Kenyatta (13:39 post).

Mr Wario said Wada’s decision was regrettable but maintained that the government would work to ensure sport was drugs free sport in Kenya and that Kenyan athletes are able to take part in Rio Olympics.

The International Olympic Committee (OIC) said there could be a number of reasons for the non-compliance ruling.

“It does not mean that the athletes will be stopped from participating in the Olympic Games,” the OIC said in statement to BBC Africa Sport.

Nairobi News has posted this video of a man hanging off the helicopter which was carrying the body of the controversial Kenyan businessman Jacob Juma, who died last week:

Mr Juma had been driving home from a bar to his home in an upmarket suburb of the capital, Nairobi, when unknown gunmen attacked his car and killed him.  

Nairobi News reports, external that Mr Juma's body was being flown to his family's home after it had been displayed for public viewing.

One tweeter said the man managed to survive:

Meanwhile the hashtag #Bungoma, the area in western Kenya where this happened, is trending on Twitter.

We reported earlier that the captain of Rwanda's national cricket team has broken a world record for batting in the nets.

He batted for 51 hours.

You'd think he would be resting up right now. But Eric Dusingizimana has other ideas.

The US embassy in Uganda has taken to Twitter to explain why its ambassador walked out of yesterday's inauguration of President Yoweri Museveni:

But some Twitter users were not going to leave it there, with many pointing out that the US hasn't itself signed up to the International Criminal Court (ICC):

But people weren't going to leave it there:

This feisty debate is taking place while access to some social media sites has been restricted. 

The government asked telecoms companies to restrict the access for security reasons.

At least 90 people have been confirmed dead in Ethiopia following days of heavy rains that have caused flash floods and landslides. 

The head of Ethiopia’s National Disaster Management Commission Mitiku Kassa told me that there would have been far more deaths if people had not been evacuated so quickly.  

The heavy rain came after Ethiopia's worst drought in decades.

Roads and bridges have been destroyed, which has made it difficult to deliver assistance to those in need.

Kenya's President Uhuru Kenyatta is currently chairing a crisis meeting with top sports officials after the country was declared to be in breach of global anti-doping rules, his government's official Twitter account says:

On Thursday the World Anti-Doping Agency (Wada) ruled the country "non-compliant" citing issues with anti-doping legislation.

This surprise move means some of the world's top athletes are at risk of missing August's Olympic Games in Rio.    

In February, Kenya missed a deadline to pass a law establishing a new national anti-doping agency so that more testing could take place – but this was passed last month.

Sports Minister Hassan Wario said Wada had now written to him attaching areas of the legislation they “want re-written or rectified for us to regain full compliance ASAP”.

“As soon as parliament reviews those highlighted bits of the legislation we are fully compliant. No ban was mentioned in the body of the letter,” he said

BBC Afrique's Sophie Ribstein captured the celebrations outside the High Court in South Africa's main city of Johannesburg today:

Families of former mine workers and their supporters cheered when they heard that the court had ruled in favour of their class action (see 09:06 post).

The ex-miners say they contracted silicosis, an incurable lung disease, after years of working in the mines. 

The ruling means that more than 40 lawyers, representing hundreds of former and current mine workers, can launch a joint case against gold mining companies.

Silicosis, caused by inhaling the silica dust in gold-bearing rocks, can lead to breathing difficulties, regular coughing and chest pains, and it can also lead to tuberculosis.

The petrol price in Nigeria has gone up by 67% this week after the government said that it was removing fuel subsidies in a bid to ease crippling fuel shortages.

The Nigeria Labour Congress (NLC) is meeting today about the hike - a litre has risen from 86.5 naira ($0.43) a litre to 145 naira.

These residents in the capital told me what they thought of the move:

Somalia says Kenya's decision to close its two biggest refugee camps is “risky” and will have serious security consequences for the whole of East Africa.

Last week, Kenya announced it would no longer host nearly 600,000 refugees, most of them Somalis.

In response, Somalia's foreign ministry has warned that the compulsory repatriation of the refugees would provide fertile recruitment ground for the Somalia-based Islamist group al-Shabab.

This would fuel terrorism rather than stemming it, Somalia said. 

The Kenyan authorities believe militants have hidden in and planned attacks in Kenya from the camps.

Three years ago, an agreement was reached encouraging Somalis to go home voluntarily, but only a few thousand have gone back.

The Somali authorities want Kenya to encourage more voluntary returns, which it describes as a safe and dignified approach.

The UN and some Western government have also appealed to Kenya not to close down the camps.   

BBC reporter in Uganda Patience Atuhaire has just told us that Facebook and Twitter are still not working in Uganda. 

She says all other sites she tried seem to be working fine.

The Ugandan communications regulator ordered mobile phone operators to block social networking sites temporarily on Wednesday.

They cited security issues ahead of Yoweri Museveni being sworn in as president.
