The International Criminal Court's Office of the Prosecutor has been monitoring allegations of war crimes committed in Afghanistan by US nationals and others since 2008. The Prosecutor has not opened a formal investigation yet but would need to present evidence to the ICC's Pre-Trial Chamber. The ICC has jurisdiction over crimes committed in Afghanistan since May 2003 when Afghanistan became a State Party. However, bilateral agreements between the US and Afghanistan require extraditing US nationals back to the US rather than the ICC. At this time, an ICC investigation is unlikely given the Obama administration's encouragement of other investigations and the lack of statements from the Prosecutor regarding an investigation.
