International Criminal Court Prosecutor Karim Khan is the first person to be hit with economic and travel sanctions authorised by US President Donald Trump that target the war crimes tribunal over investigations of US citizens or US allies, two sources briefed on the matter told Reuters.

Khan, who is British, was named on Friday in an annex — not yet made public — to an executive order signed by Trump a day earlier, a senior ICC official and another source, both briefed by US government officials, told Reuters.
