Alieu Kosiah is a former commander of the United Liberation Movement of Liberia for Democracy (ULIMO) faction, a rebel group that participated in the First Liberian Civil War (1989-1996) which fought against the National Patriotic Front of Liberia, led by Charles Taylor. After the war, Kosiah moved to Switzerland, where he obtained permanent residence.

On 10 November 2014, Swiss authorities arrested Kosiah in connection with accusations that he was involved in mass killings in parts of Liberia’s Lofa County from 1993 to 1995. Criminal complaints were filed against him by several Liberian victims, represented by Alain Werner, Director of Civitas Maxima. Kosiah was accused of ordering civilian massacres, rapes, and other atrocities in northern Liberia during the nation’s First Civil War.

Kosiah was charged on several counts, including having ordered, committed, or participated in the murder of civilians and soldiers hors de combat, having desecrated the corpse of a civilian, having raped a civilian, having ordered the cruel treatment of civilians, having recruited and used a child soldier, having ordered several pillages, and having ordered and/or participated in the forced transport of goods and ammunition by civilians.

The Swiss Federal Criminal Court postponed the trial several times due to the spread of COVID-19.  Finally, the Court has decided to proceed with the preliminary questions and the hearing of the defendant from December 3 to December 11, 2020. The rest of the trial – the hearing of the plaintiffs and the witnesses, and the final pleadings – took place from February 15 to March 5, 2021. A verdict is expected by the end of June 2021.

This was the first time a Liberian national was tried for war crimes in relation to the Liberian Civil Wars, and the first time the Federal Criminal Court held a war crimes trial.
