British barrister Karim Khan, 51, took over as the International Criminal Court's top prosecutor yesterday with a pledge to improve its track record by taking only its strongest cases to trial. The ICC is handling a number of sensitive cases, including in the Palestinian territories and Afghanistan, and members of the prosecutor's office were personally targeted by financial sanctions while Donald Trump was US president. Khan, 51, took an oath to serve his nine-year term honourably and impartially during a ceremony in The Hague.  Already short of resources, the ICC is dealing with 14 full-blown investigations and eight preliminary examinations. Khan also inherits investigations opened in countries including Myanmar, the Philippines and Ukraine.
