Six people have been arrested in South Africa over the shooting of a Rwandan dissident, police say.Meanwhile, a prominent Congolese Tutsi and CNDP leader, Denis Ntare Semadwinga, was killed on Sunday night in Gisenyi, the town that sits just over the Rwandan border from Goma. Jason Stearns has details and analysis here.
Police spokesman Govindsamy Mariemuthoo refused to give the nationalities of the suspects but said more arrests were likely.
...Rwanda has denied any involvement in the shooting in Johannesburg.
The BBC's Karen Allen in Johannesburg says a Rwandan national known to Lt Gen Nyamwasa is believed to be among those detained.
Suffice it to say that none of this bodes well for the prospects for regional peace.
