There has been a second outbreak of fighting this week in the Republic of Congo's capital, Brazzaville.
Government spokesman Alain Akouala said gunfire and rockets were exchanged overnight between two Ninja rebel factions in the south of the city.
But rebels say they were attacked by government soldiers. Calm has returned and shops have opened as usual.
In March, a peace deal was signed with the Ninjas, whose stronghold is in the Pool region, south of the capital."
right now, there is something quietly surreal about this, and i can't escape the image of black clad men with swords going at each other in that ninja way. not true, naturally, since they're really just a militia group with a bit of a fixation on the whole japanese thing. but still, it's surreal. the more you look at the news report, the more you think someone in the bbc has changed the name of the rebel group to ninja just for a bit of fun.
