The CNN headline is a bit misleading. It’s not the International Criminal Court as a whole that is seeking these arrest warrants but the ICC’s chief prosecutor Karim Khan. The judges have yet to decide on these warrants.
[Side note: This is the same kind of lazy journalism that uses terms like EU chief or EU leader interchangeably for the President of the European Commission (Ursula von der Leyen) and the President of the European Council (Charles Michel). If this was limited to a short headline, I could excuse it, but CNN continues with the same wording in the first sentence of the article: “The International Criminal Court is seeking arrest warrants for …” which is absolutely unnecessary, even if CNN clarifies things later.]
