Parties to the International Criminal Court on Friday elected Britain’s Karim Khan as the new prosecutor for a nine-year term starting on June 16.

Khan won a secret ballot against three other candidates to replace lead prosecutor Fatou Bensouda. The 123-member Hague-based court, which began work nearly 20 years ago, handles war crimes, crimes against humanity, genocide, and crimes of aggression.

British barrister Karim is best known for heading the United Nations’ special investigative team looking into Islamic State crimes in Iraq.

In his 27-year law career Khan, who is also Queens Counsel, has worked for almost every international criminal tribunal in roles in prosecution, defense and as counsel for victims. At the ICC Khan is best known for being a lead defense counsel who has worked on cases from Kenya, Sudan and Libya.

There was intense political jostling for the top ICC job at a time of heightened scrutiny of the prosecutor’s office.

Former US President Donald Trump’s administration imposed sanctions last year on court staff including Bensouda over investigations by her office into possible war crimes committed in Afghanistan, including by American troops. The United States is not a member of the court.

New US President Joe Biden’s administration will “thoroughly review” the sanctions on ICC officials, a State Department spokesman said last month.

Then last week the court said it has jurisdiction over war crimes committed in the disputed territories, which could lead to an inquiry strongly opposed by non-ICC member Israel and the United States.

One of the first decisions by Khan could be whether to press ahead with a full investigation into the disputed territories, where Bensouda said there is a reasonable basis to conclude war crimes may have been committed by both Israeli forces and Palestinian armed groups.

“Karim’s extensive experience in international law will be pivotal in ensuring we hold those responsible for the most heinous crimes to account and gain justice for their victims,” Britain’s Foreign Secretary Dominic Raab posted on Twitter.
