The former leader of South Africa's main opposition Democratic Alliance (DA) has resigned from all leadership positions in the party, in the latest fall-out from her controversial tweets about colonialism.

The DA made the announcement at a joint press conference that Helen Zille held with Mmusi Maimane, her successor and the first black leader of the party.

Mr Maimane said he was angered by Ms Zille's tweets, and leaders should remember that colonialism was not a "victimless crime".

Mr Maimane said Ms Zille had agreed to offer a "fulsome and unqualified" apology to South Africans.

Ms Zille was giving up her posts on the DA's Federal Executive, Federal Council and Provincial Council, as this was in the best interest of the party, Mr Maimane added.

However, she remained the premier of the Western Cape province.

She would no longer be able to comment on issues unrelated to her government post without abiding by the "sign-off protocols of the DA", Mr Maimane added.

The agreement with Ms Zille drew a line under the "unfortunate episode", and avoided a protracted legal battle, he added.

In her comments, Ms Zille said her priority now was to restore public trust.

She added that that given South Africa's history “the origin of the speaker makes a difference to what is being heard and I think this is one of those cases.”

Her tweets caused a storm in March, raising fears it wll damage the DA's chances of winning support among black voters in the 2019 election.

She said the legacy of colonialism was not all negative, and added: "Would we have had a transition into specialised health care and medication without colonial influence? Just be honest please."

Kenyans enjoy faster mobile internet speeds than American, Taiwanese, Irish and Swedish citizens, according to a report by technology firm Akamai.

Overall, the East African country ranks 14th of the 130 countries surveyed.

Kenyan internet specialist Njeri Rionge explains to BBC Africa's David Amanor why this comes as no surprise to many in the sector.

The Moroccan government has said it is sending a plane-load of food to Qatar, which has been isolated by transport restrictions imposed by its Gulf neighbours.

In a statement, the Moroccan foreign ministry said the move was only humanitarian and unrelated to the political dispute over Doha's alleged links to terrorism.

Earlier, the king of Morocco, Mohamed VI, offered to mediate between the parties. Last week Morocco suspended flights to and from Doha.

Qatar relies on imports for most of its food.

Zimbabwe has banned grain imports to protect local farmers after producing enough to meet domestic demand, the deputy minister of agriculture has said, just a year after a devastating drought left more than 4 million people in need of food aid.

Its grain agency has also raised $200 million (£160m) from the government and private sector to purchase maize from farmers, state-owned media reported.

The treasury last week forecast output of the staple maize at 2.1 million tonnes this year, from 511,000 tonnes in 2016.

Reuters news agency quoted the deputy minister of agriculture, Davis Mharapira, as saying:

Mr Mharapira said the state's Grain Marketing Board would pay $390 per tonne for white maize, almost triple the $143 for the September contract for white maize in South Africa, one of the countries from which Zimbabwe has previously imported maize.

He added that the higher price would encourage farmers to produce more maize while the import ban would make it impossible for dealers to buy the grain abroad and resell it at a higher price locally, Reuters reports.

Zimbabwe has since 2001 been importing maize to meet domestic demand of 1.8 million tonnes. The crisis has been blamed in part on the seizure of white-owned farms, hitting commercial agriculture production.

About 15 people are missing after a seven-storey building collapsed on Monday night in an eastern neighbourhood of the Kenyan capital Nairobi.

The Kenya Red Cross has tweeted that response teams are on the scene at the building:

Police were called to the scene moments before the incident. The officers then ordered an evacuation.

The National Disaster Management Unit says most families heeded the call and 121 people left the building safely.

Local media reports that some people sneaked back into the building apparently to collect their belongings but then it caved in while they were inside. Rescue efforts are under way.

This is not the first time a residential building in Nairobi has collapsed.

An audit by the National Construction Authority in 2015 found that just over half of the buildings in the city, particularly in low-income areas, are unfit to live in.

Authorities have in the past promised to demolish substandard buildings, but no such action has been taken.
