Human Rights Watch is hailing a “monumental victory” after a Swiss court convicted former Gambian Interior Minister Ousman Sonko for crimes against humanity committed under the dictatorship of Yahya Jammeh. Sonko was sentenced to 20 years in prison for his role in torture, illegal detentions and unlawful killings between 2000 and 2016. He is the second ex-Gambian official convicted in Europe for international crimes committed in Gambia, after a former death squad member received a life sentence in Germany last year.
