When it comes to social media's heavy hitters, there are no bigger players than Facebook or Twitter, right? Not if you're in South Africa. Mobile network Mxit claims to have nearly 10 million users in the country, making it South Africa's most popular social media platform by far, eclipsing Facebook's six million users and Twitter's 1.1 million subscribers. Founded seven years ago by Namibian-born software developer Herman Heunis, Mxit has grown from an instant messaging application into a global mobile social network.

South African police have been accused of planting weapons near the bodies of workers killed during strikes at the Marikana platinum mine. Photographs taken by police suggested large knives had been placed near the bodies after they had been shot, a lawyer told an inquest into the deaths. Thirty-four miners were killed when police opened fire on the striking workers at the mine in August.

A Magistrates’ Court in Ouagadougou, the capital, on October 29, 2012 sentenced Roland Ouédraogo and Issa Lohé Konaté, both editors of privately-owned L’Ouragan newspaper to 12 months in prison on charges of defaming Placide Nikieme, the State Prosecutor. According to the Media Foundation for West Africa’s (MFWA) correspondent the sentence followed a complaint lodged by Nikiema at the Court accusing the newspaper and its editors of defaming him in a published article, which cited corrupt practices in the State Prosecutor’s office.

Pansy Tlakula, the African Union’s Special Rapporteur on Freedom of Expression and Access to Information, has done her best to address the continued harassment of journalists in the Gambia. In her role as commissioner of the African Commission on Human Peoples’ Rights, she has appealed many times to the government of the West African nation to respect people’s right to freedom of expression. But it has not been enough to prevent the Gambian government’s crackdown on the media.

Already struggling to access sporadic humanitarian assistance, internally displaced people (IDPs) in the Somali capital Mogadishu are also facing eviction by returning landowners and unscrupulous camp 'gatekeepers' who siphon away what little aid is received, a new report says. When [insurgent group] Al-Shabab gave up control of the Somali capital, militia leaders, politicians and influential landowners re-consolidated their control over various parts of the city. This control extends to the displacement camps where international humanitarian assistance is directed,' notes the report, 'Gatekeepers and Evictions: Somalia's Displaced Population at Risk', by Refugees International (RI).

Uganda's authorities have banned a play that criticises President Yoweri Museveni's government, the play's co-director John Ssegawa has said. He said the Media Council had ordered performances of State of the Nation to be halted until a review was held.

Uganda’s practice of pardoning and then integrating into its military captured or surrendered members of the Lord's Resistance Army (LRA), getting them to hunt down their former comrades-in-arms, has come in for criticism by civilians affected by the rebel group in the Central African Republic (CAR). 'This strategy is a real insult to the victims,' said Gaétan Zangagoumé, chairman of a victims’ association in Obo, capital of Haut-Mbomou Prefecture. The area, in the extreme southeast of CAR, has been heavily affected by LRA activities. Victims there include hundreds of civilians forcibly conscripted into the LRA as well as people from villages repeatedly attacked, torched and now deserted. Fear of further attacks greatly restricts freedom of movement.

If there is such a thing as an African version of California's Silicon Valley, the country that is arguably leading the race to the future is Kenya. Household tech names such as Google, Intel, Microsoft, Nokia and Vodafone all have a presence here, and IBM recently chose Nairobi for its first African research lab. Kenyans enjoy faster broadband connections than their counterparts in Africa's economic powerhouse, South Africa. And the government plans to build a $7bn (£4.36bn), 5,000-acre technology city that is already being branded Africa's 'Silicon Savannah'.

The International Monetary Fund (IMF) has eased technical assistance restrictions on Zimbabwe in a move seen as moving towards normalising relations with the southern African nation.

Reporters Without Borders says it is deeply concerned by death threats received in e-mails by the journalists Baboucarr Ceesay and Abubaccar Saidykhan, against whom charges of conspiracy and inciting violence were dropped earlier this week.

The chief prosecutor of the International Criminal Court has visited victims of the violence that followed Kenya's 2007 election. Fatou Bensouda says she was concerned about ICC witnesses being intimidated ahead of a criminal trial at The Hague in the Netherlands.
