An independent United Nations human rights expert today voiced his deep concern over the diminishing freedom of expression and association in Burundi, warning that violations of these freedoms imperil the rule of law in the African Great Lakes country. “The Government must restore a calm political climate and take all necessary measures to end the harassment and intimidation of journalists and representatives of civil society, trade unions and political parties,” said Akich Okola, the Independent Expert on the situation of human rights in Burundi.
