In Rwanda, a deadly fight among the ruling elite

The mourners who railed against Patrick Karegeya's killers spoke of them as if they knew exactly who they were.

Officials in Rwandan President Paul Kagame's government carried out the killing, some whispered in private, but none dared say so in public at a requiem in Uganda for the former Rwandan spymaster who was found dead in a Johannesburg hotel earlier this month.

Other former allies of Kagame's government have died suspiciously or been murdered after leaving the country, fueling speculation of retaliation.
