Zimbabwe's First Lady Grace Mugabe has not been officially charged over the alleged assault of a 20-year-old model in a hotel in Johannesburg's upmarket suburb of Sandton.

According to police, she was expected to present herself for questioning, but this has not yet happened.

The authorities will want to play this one carefully. Mrs Mugabe is not an ordinary person. They will need to determine whether as Zimbabwe's first lady, she travelled to South Africa on a diplomatic passport.

We understand Mrs Mugabe’s lawyers and South African authorities are in negotiations on how to proceed.

Mrs Mugabe's whereabouts are unclear and there are unconfirmed reports that she returned to Zimbabwe earlier this afternoon.

It is important to note that at this stage her movement is not restricted.

Nevertheless, authorities in South Africa will be keen to hear her version of events. Prosecutors say investigations are at an “advanced stage” but they cannot act until the docket is finalised.

The much-anticipated announcement by defeated Kenyan opposition leader Raila Odinga on his next course of action, after rejecting the results of last week's presidential poll, has been postponed. The official results put the incumbent Uhuru Kenyatta as the winner with just over 54% of the vote.

A senior official of the opposition Nasa alliance, Musalia Mudavadi, told the BBC that the “major announcement” will now be made on Wednesday.

Mr Mudavadi said the opposition leaders were currently engaged in intense closed-door consultations with a view to reaching an amicable agreement on the way forward for the alliance.

President Abdelaziz Bouteflika of Algeria has sacked Prime Minister Abdelmadjid Tebboune, who had been in the job for less than three months.

No reason was given for the dismissal. But it came just days after the president sent Mr Tebboune a strongly worded letter demanding changes in policy.

The new prime minister has been named as Ahmed Ouyahia, who has served as the president's chief of staff.

Analysts say he is likely to be seen as a steadying influence as Algeria tries to adjust to lower oil prices.

Relatives, friends and journalists braved the morning cold to welcome home Kenya’s athletics team from the World Championships in London.

Freetown is a city squeezing itself into the small space between the mountains and the sea, in a country with one of the highest levels annual rainfall in Africa.

In August - the height of the rainy season - an average of 539.9mm falls on Sierra Leone's capital.

So it comes as no surprise that Freetown is a city used to flooding.

But Monday's rain brought with it a disaster which left hundreds dead, and will no doubt be followed by finger-pointing and blame shifting.

Was it simply the effects of climate change and geography, or something more avoidable?

South Africa's governing African National Congress (ANC) will discipline party members who publicly stated that they voted with the opposition in the failed bid to oust President Jacob Zuma, ANC secretary-general Gwede Mantashe has said.

However, the ANC will not embark on a "witch-hunt" to identify MPs who voted against the president in the secret ballot, Mr Mantashe said.

He added:

The 8 August no-confidence motion in the scandal-hit Mr Zuma was defeated by 198 votes to 177 in parliament.

About 30 ANC MPs defied a three-line whip, instructing them to vote for Mr Zuma, according to South African media.

The opposition called for his removal from power atfer accusing him of being corrupt, and of wrecking the economy. The ANC said the no-confidence motion was an attempt by the opposition to usurp power.

Mr Zuma has found himself embroiled in a number of scandals since taking office in 2009, including using taxpayer money for upgrades on his private home, and becoming too close to the wealthy Gupta family, who are accused of trying to influence decisions in his government.

Both Mr Zuma and the Gupta family deny wrongdoing.
