Prosecutors in the Netherlands are considering a request to open a criminal case against senior Israeli intelligence officials for allegedly interfering with an investigation by the international criminal court (ICC).

The request was filed last week by a group of 20 complainants, most of whom are Palestinian, asking the Dutch prosecution service to examine allegations Israel tried to derail the ICC’s inquiry into alleged crimes in the occupied Palestinian territories.

According to lawyers for the group, the criminal complaint was filed in response to an investigation by the Guardian revealing how Israeli intelligence attempted over a nine-year period to undermine, influence and allegedly intimidate the ICC chief prosecutor’s office.

The joint investigation with the Israeli-Palestinian publication +972 Magazine and the Hebrew-language outlet Local Call prompted the Dutch government to raise concerns earlier this year with Israel’s ambassador to the Netherlands.

As the host state of the ICC, which is in The Hague, the Netherlands is obliged under an agreement with the court to protect the safety and security of ICC staff, and must ensure it is “free from interference of any kind”.
