Sierra Leone’s top 100m sprinter has had his application to remain in the UK denied, and been given until Monday to leave the country or face arrest, the UK's Guardian newspaper reports, external. 

Jimmy Thoronka had hoped to start his studies at The University of East London, which offered him a scholarship in September, contingent on him getting a visa to remain in the UK.

For any online Nigerians, who might be feeling bruised after being told by their president in his Independence Day speech to curb their "unruly behaviour" (see post at 13:38), Google may have provided a small patriotic boost.

Dianne Kohler Barnard, an MP for South Africa’s main opposition Democratic Alliance (DA) party, has apologised for a Facebook post she shared, saying she did not read it properly.

The post praised apartheid leader PW Botha and called for his return and also said that during his time, education, health and the police services were better than they are in modern South Africa - and has been shared on social media:

The hashtag #kohlerbarnard is now trending in South Africa and the DA leader has also tweeted:  

The timing could not be worse for the DA as it struggles to broaden its appeal beyond perceptions that it represents white South Africans.

The governing African National Congress (ANC) spokesman accused Ms Kohler Barnard and the DA of apologising under pressure.

“These are the true colours of a chameleon coming out slowly,” Zizi Kodwa said.

“It’s 21 years into democracy and we have people who cannot hide their feelings for PW Botha who caused so much misery.

“The DNA of the DA is racist… They elected Mmusi Maimane to be leader as a black man precisely to hide this racism.”

"The variety of what you can do in Nigeria knows no bounds.... an amazing time... sadly dominated by the terrible scenes from the north-east, which have meant we haven't had as much of the rest of Nigeria."   

Will Ross has been reflecting on his nearly four years in Nigeria, as his BBC posting comes to an end.

South Africans have been reacting to the naming of scrum-half Fourie du Preez as the new captain of the Springboks rugby team. 

He'll lead South Africa in their World Cup match against Scotland on Saturday, following the retirement of previous captain Jean de Villiers, who broke his jaw during the Springboks' 46-6 victory over Samoa.

Followers of South Africa's Super Sport TV seem happy enough with the decision. In an online poll, 72% have agree that Du Preez is the right man for the job: 

Swedish Pilot Johan Wiklund has set off on an old-fashioned adventure retracing an epic flight from 1929. 

His hero, Gosta Andree, flew from Norway's North Cape all the way to the Cape of Good Hope in South Africa. 

Now Johan has taken on the challenge on a 1935 De Havilland Moth biplane. 

He has now reached the Kenyan capital of Nairobi - about two-thirds of the way into his journey, from where he's been speaking to the BBC's Newsday programme.

Award-winning Somali journalist Jamal Osman has written a piece for the UK's Guardian newspaper, criticising the decision to send British troops to Somalia. 

UK Prime Minister David Cameron announced this week that 70 soldiers will be sent to support the African Union peacekeeping force, which is battling the Islamist militant group al-Shabab.  

Mr Osman writes:

"The very real possibility, however, is that Britain may end up helping the jihadi to build their support among local people...

"Al-Shabab was born when Ethiopia invaded Somalia in 2006 and some still see the group as a resistance movement. That is why deploying British troops could help these militants recruit more fighters and receive financial and moral support."  

There have been four confirmed cases of Ebola reported in the week until 27 September, all in Guinea. Two of the four new cases are traditional healers who are reported to have treated a 10-year-old girl who died, the World Health Organization says.
