Kenya's athletics manager, who was sent home from the Rio Olympics, is to be held by police for four weeks as they investigate allegations that he had warned athletes about drugs tests in return for cash, Reuters news agency has reported.

A court has approved a police request to keep Michael Rotich, who had requested bail, in custody.  

Mr Rotich has denied the accusation published in the UK's Sunday Times, which said he had been filmed by undercover journalists, posing as athlete representatives, some months ago.

Flower-carrying demonstrators in Zimbabwe gathered in central Harare today to demand that the whereabouts of missing prominent pro-democracy human rights activist Itayi Dzamara.

He has not been seen since he was abducted by five men in Harare in March 2015.

Officials have denied any state agents were involved in his abduction.

The marchers blew whistles and walked towards the anti-riot police, but unlike scenes seen last week when officers attacked demonstrators calling for President Robert Mugabe to leave office, the police remained calm and returned to their vans.

Burkina Faso has seen its donkey-hide trade with China soar in recent years, but it has now banned all exports (see earlier post).

The reason behind the booming trade is perhaps the demand for gelatin, made by boiling donkey skin, which is highly prized in China as a medicinal tonic. It is thought to nourish the blood, boost the immune system and act as a general pick-me-up.  

It is sometimes referred to as one of the "zi bu san bao", meaning three nourishing treasures, along with ginseng and the antlers of young deer. 

Donkey gelatin is sometimes mixed with walnuts, goji berries and other tonic foods and sold in dark, gummy slabs that can be eaten as a snack. 

Health and longevity is a Chinese national obsession, and tonic foods like this are often lavishly packaged and presented as expensive gifts.

Aside from gelatin, donkey meat is a delicacy in some Chinese regions, especially in the north of the country where it is often simmered in a richly spiced broth, and then cooled, sliced and served with a refreshing dip of chopped garlic and vinegar. 

In northern Hebei province, one famous snack is the "lu rou huo shao", in which chopped, spiced donkey meat is mixed with fresh green chilli and stuffed into a layered pastry: Its name is  sometimes translated into English as a "donkey burger". 

Libyan forces battling to oust so-called Islamic State (IS) from Sirte say they have made significant gains, taking control of a large convention centre previously used as a base by the militant group.

"Our forces have complete control of the whole of the Ouagadougou [convention] complex - they even advanced some distance beyond the complex," Reuters news agency quotes Rida Issa, a spokesman for the forces, as saying

Sirte's hospital and university compound had also been captured, he said.

According to the AFP news agency, capturing the Ouagadougou centre has been the key goal of the anti-IS forces.

The son of the Central African Republic's (CAR) ousted leader Francois Bozize has been released on bail.

Jean-Francois Bozize was the defence minister in his father's cabinet when mainly Muslim Seleka rebels took power in 2013.

He is accused of being involved in the violence committed in the following years by the mostly Christian anti-balaka militias thought to be close to his father.  

He went into exile and international arrest warrant was issued for him.

But he returned to CAR last week and handed himself in to the UN mission.

He faces charges including involvement in extra-judicial killings, torture and corruption. 

His lawyer says there is no evidence against him – and he will respond to the allegations during his trial.
