The new sanctions target Kimberly Prost of Canada, Nicolas Guillou of France, Nazhat Shameem Khan of Fiji and Mame Mandiaye Niang of Senegal.

Guillou is an ICC judge who oversaw a pre-trial panel that issued the arrest warrant for Netanyahu, while Khan and Niang are the court’s two deputy prosecutors. The US Department of State cites the role all three played in issuing and upholding the Israeli arrest warrants.

The ICC is also probing possible war crimes by US forces in Afghanistan, although it said it will prioritise abuses by the Taliban and ISIL (ISIS) in that investigation after fierce US pushback.
