Rwandan President Paul Kagame says it's a matter of time before those who've betrayed Rwanda face consequences.

The comments come nearly two weeks after the murder of a former Rwandan spymaster turned dissident.

The body of the former head of Rwanda's external intelligence service, Col. Patrick Karegeya, was discovered in a Johannesburg hotel on New Year's Day. South African Authorities believe he was strangled. Kagame's critics accuse him of ordering the assassination. Government representatives have not denied or accepted responsibility.

Kagame said Sunday: "You cannot betray Rwanda and get away with it. There are consequences for betraying your country."

Karegeya, a wartime ally from Kagame's days as a rebel leader, fled to South Africa in 2007.
