A prominent member of the Rwandan refugee community in Mozambique, who had told police there was a plot to kill him, has been shot dead.
Révocat Karemangingo had been a lieutenant in the Rwandan army that was overthrown in 1994 by forces led by President Paul Kagame.
In Mozambique he became a businessman and was not involved in politics, the leader of the refugee community said.
The Rwandan government has been accused of targeting opponents living abroad.
It has consistently denied the allegation.
Mr Karemangingo, who was the treasurer of the Rwandan refugee association, was driving to his home near the Mozambican capital, Maputo, when his car was ambushed on Monday.
