Nigeria's first lady has warned that "hyenas and jackals" will be banished in a cryptic Facebook post apparently aimed at her husband's officials.

Aisha Buhari's comments seem to be directed towards powerful ruling party politicians, says the BBC's Naziru Mikailu, in the capital Abuja.

The senior politicians appear to be suspected of manoeuvring for the presidency or deputy presidency while her husband is ill.

President Muhammadu Buhari has been in London since May receiving treatment.

The vice-president has been acting in his place while he is out of the country, but there is no suggestion he is part of any plot against Mr Buhari.

Mrs Buhari, who is also in London, says her 74 year old husband is recuperating well.

Today is World Population Day - and one man in Ghana has 100 reasons to mark his particular contribution.

Kofi Asilenu, 80, is the father of 100 children by 12 wives.

He lives with his family in a village called Amankrom, a 45-minute drive from the capital Accra.

His family make up a third of the 600 people in the village.

He told me that he wanted a big family because he did not have siblings:

His big family has, however, come at a cost. He says that he was well off financially, but his resources have mostly been drained due to the cost of raising such a large brood - even though he says now he gets financial help from his children.

Kofi Asilenu looks physically strong and even says he is willing to have more children - despite having mistakenly proposed to one of his daughters three years ago.

The embarrassing incident meant he was forced to apologise to her, explaining that he had an eye problem so he could not recognise her.

As for his wives, they are all happy with the set up.

First wife Nayome Asilenu told the BBC:

Polygamy was preferred in Ghana, to have many children was seen as a symbol of wealth. However, things have changed with women having more control on deciding how many children they can have and also birth control measures have been promoted nationwide.

This news has not come as a surprise as it has long been accused of incompetence.

While dissolving the council, the sports minister Harrison Mwakyembe, said their failure to improve sports in the country had nothing to do with a shortage of funds but rather out of negligence.

He also accused the council’s operation of being dominated by corruption.

However the former Secretary General of the council Mohammed Kiganja denies this:

The shut down of the council comes just a fortnight after the president and other top officials of the country’s football federation were charged with money laundering.

South Africa's Communist Party (SACP), a key ally of the ruling African National Congress (ANC) has banned President Jacob Zuma from addressing its congress this week, the party spokeswoman told AFP news agency reports.

Hlengiwe Nkonyane said the decision was based on Mr Zuma's political problems:

"We advised the ANC that due to the tensions we are having... it would be best for the president not to address the national congress."

It will be the first time that President Zuma, who came to power in 2009, has not addressed the congress, held every four years, AFP reports.

SACP has been increasingly critical of Mr Zuma and called on him to step down over his alleged scandals and his connections to the controversial Gupta family, which is said to have undue influence over his government, a situation that has negatively affected ANC's public support.

In May, he was forced to abandon a rally after he was jeered by the crowd, and the SACP said it did not want the same to happen at its event.

The SACP, along with the ANC and the trade union federation Cosatu, was at the forefront of the struggle to end white-minority rule that led to the first non-racial elections in 1994.

Mr Zuma will on 8 August face a motion of no-confidence in parliament called by the opposition.

He is due to step down as ANC leader in December and as national president ahead of the 2019 election.
