A former member of Belarusian President Aleksander Lukashenko’s special security forces was going on trial Tuesday in Switzerland over the enforced disappearances of political opponents in the late 1990s — seen as a landmark case of international justice. Yuri Harauski, a former member of a military unit known as SOBR, exited a tinted-window van wearing a hood as he entered the courthouse in the northern city of St. Gallen. Activists have said the two-day trial marks a pivotal moment in international justice that could trigger prosecutions abroad of other Belarusian officials — including Lukashenko.
