The UK will soon impose sanctions on Rwanda over its alleged support for the M23 rebel group, which has seized territory in eastern Congo, including key cities and mineral-rich areas. Britain will introduce sanctions soon against Rwanda over fighting in neighbouring Congo, a minister in the UK Foreign Office told Reuters on Monday.

When Rwanda's ex-spy chief Patrick Karegeya was murdered in South Africa in 2014, his former brother-in-arms James Kabarebe was blunt: "When you choose to be a dog, you die like a dog."

On February 16th soldiers from M 23 marched single-file through the streets of Bukavu, eastern Congo’s second-largest city. The beleaguered remains of the Congolese army had retreated without a fight. Rebel fighters toting grenade-launchers and machine-guns took triumphant selfies in the city’s main square.
