El Salvador puts 486 MS-13 leaders on trial for 29,000 killings in process Bukele compares to Nuremberg El Salvador launched in late April the largest trial in the country's history against 486 alleged leaders of the Mara Salvatrucha-13, accused of ordering more than 29,000 killings committed between 2012 and 2022, in a process President Nayib Bukele described as "historic" and compared to the Nuremberg trials against Nazi leaders after the Second World War. The proceedings, held before a specialized tribunal with anonymous judges, represent the first case worldwide in which the "command responsibility" principle has been applied to a gang structure.
