A United States federal court has convicted South Sudanese activist Peter Biar Ajak on charges linked to an attempt to illegally acquire and export weapons from the United States.
According to federal prosecutors, Ajak was involved in a coordinated scheme to purchase military-grade firearms and related equipment within the U.S. and unlawfully ship them abroad. Authorities said the intended destination was South Sudan, a country subject to strict international arms restrictions.
Prosecutors argued that the operation violated multiple U.S. federal laws, including statutes governing arms export controls and conspiracy to commit export-related offenses. The court agreed, finding that the actions breached both domestic regulations and international arms embargoes.
During the trial, the government presented evidence showing efforts to bypass legal export procedures and conceal the true destination and intended use of the weapons. The court ruled that these actions posed serious national and international security concerns.
At sentencing, the presiding judge imposed a 46-month federal prison sentence. However, the court also acknowledged the lengthy period Ajak has already spent in custody during the investigation and trial process.
After crediting time already served, Ajak is expected to serve approximately 22 more months, equivalent to about one year and ten months, before becoming eligible for release, subject to standard federal regulations.
The conviction has attracted wide attention, particularly among South Sudanese communities at home and in the diaspora. Supporters point to Ajak’s long history as a political activist, while critics argue that the case underscores the seriousness of international arms control laws, regardless of an individual’s political background.
Legal analysts note that U.S. courts treat export control violations with particular severity, especially when they involve conflict zones or embargoed countries. The case is expected to have broader implications for activists and organizations operating across borders.
