Should he stay or should he go? When it comes to the president, it's the subject of heated debate in Burundi, Congo, DR Congo and Rwanda.

The detention of Rwanda's intelligence chief in London belongs to the murky area where transnational justice meets political interest, and perhaps also sheer incompetence.

A BBC documentary on Rwanda produced great controversy, including in an article by Andrew Wallis. But his own critique is itself selective and inaccurate in important ways, replies one of those he criticised.

A deeply flawed BBC documentary on Rwanda's genocide raises serious questions over the corporation's ethics and standards.

Shattered societies cannot be mended with pills or analysis or technology or foreign aid. Our need to hear that Rwanda is ‘healing’ tells us more about ourselves than it does about Rwanda.

Two decades after the Rwanda genocide, the promised hopes of international accountability for such crimes is in trouble. Andrew Wallis examines the ingredients of a crisis that is both legal and political.

The belated trial of a suspected genocidaire in Paris highlights the complex political relationship between Rwanda and France. It also reflects problems in the hard road to international justice, says Andrew Wallis.

The Rwandan government have ambitious yet deeply disruptive plans to rebuild Kigali as Africa's Singapore.  Despite plans to uproot vast swathes of the city to make way for 'virtual Kigali', the response by ordinary city-dwellers has been one of striking silence. 

The tribunals judging crimes in Rwanda and former Yugoslavia were intended to deliver justice for victims of genocide. But several recent cases suggest that politics may be getting in the way, says Andrew Wallis in Kigali.

The UN Refugee Agency must not be the facilitator of a permissive attitude towards continued corruption and the absence of democracy in Rwanda. By calling on refugees who fled before 1998 to return home to the threat of persecution it risks legitimising Kagame’s autocratic regime.

Violence in eastern DRC is portrayed by western countries in terms of abject failure: people or events in the Congo (or Rwanda) have caused peacebuilding and development processes to fail. But the M23 is a direct result of processes that legitimate violent power. Français.

Though triggered by a combination of recent events, the pre-colonial, colonial and post-colonial history of the Kivus sets the stage on which they take shape. Understanding is not justification: beware the instrumentalisation of history by ideologues. Français.

The military and political tensions in the contested eastern region of the Democratic Republic of Congo are reinforced by diplomatic failures. A turn towards negotiation and compromise is vital if the area's long-term problems are to be addressed, says Andrew Wallis. 

L'éruption de violence dans l'est de la République Démocratique du Congo reflète l'échec des organisations nationales et internationales sur le long terme, affectant les citoyens de la région ainsi que les communautés de la diaspora européenne. Pour sortir de ce cycle, il faudra s'en prendre aux racines de la violence. Read this in English.

An eruption of militia-based violence in the eastern Democratic Republic of Congo reflects a longer-term pattern of failure by national and international agencies. The effects are now being felt among diaspora communities in Europe as well as citizens in the region. The roots of violence must be addressed if the cycle is to be ended, says Andrew Wallis. Français.

Many of the drivers of conflict in eastern DR Congo lie within its borders, but an analysis that ignores the role of Rwanda in recent years is inadequate to the task of disassembling the cycles of violent insurrection. Français.

Beaucoup des facteurs de conflit dans l'est de la République Démocratique du Congo se trouvent à l'intérieur de ses frontières mais une analyse qui ignorerait le rôle du Rwanda ces dernières années ne permettrait pas de démonter le mécanisme des cycles d'insurrection violente. Read this in English.

A rise in violent tension in the east of the Democratic Republic of Congo, across the border from Rwanda, is the latest phase of a conflict unresolved since the Rwandan genocide of 1994. The wider story it tells is one of state failure in the DRC, says Andrew Wallis.

M23's military campaign in North Kivu has profound consequences for Kinshasa and regionally. A regional military force to end the rebellion is hotly disputed: Rwanda and Uganda have interests in the instability, while placing any more foreign troops into this volatile region holds great uncertainty.

Why has the Arab Spring so far failed to spread south of the Sahara – and should some African leaders be looking over their shoulders?
