Human Rights Watch is urging Uganda's government to conduct a "transparent" investigation into the murder of a Rwandan journalist.
The group said in a statement Tuesday that Uganda's government should provide protection for Rwandan journalists and other critics of Rwanda's government living in Uganda.
Charles Ingabire, the editor of an online publication and a frequent critic of Rwanda's government, was shot and killed in Kampala last week.
Critics of the government of Rwanda President Paul Kagame have been killed under mysterious circumstances over the years. Rwanda's government has always denied any involvement in such deaths.
Human Rights Watch's Daniel Bekele said that the persecution of critics of Kagame's government can reach beyond Rwanda's border. He said his group fears for the safety of other exiled journalists and government opponents.
