Spying, hacking and intimidation: Israel’s nine-year ‘war’ on the ICC exposed

When the chief prosecutor of the international criminal court (ICC) announced he was seeking arrest warrants against Israeli and Hamas leaders, he issued a cryptic warning: “I insist that all attempts to impede, intimidate or improperly influence the officials of this court must cease immediately.”

Karim Khan did not provide specific details of attempts to interfere in the ICC’s work, but he noted a clause in the court’s foundational treaty that made any such interference a criminal offence. If the conduct continued, he added, “my office will not hesitate to act”.

The prosecutor did not say who had attempted to intervene in the administration of justice, or how exactly they had done so.

Now, an investigation by the Guardian and the Israeli-based magazines +972 and Local Call can reveal how Israel has run an almost decade-long secret “war” against the court. The country deployed its intelligence agencies to surveil, hack, pressure, smear and allegedly threaten senior ICC staff in an effort to derail the court’s inquiries.

A hand-delivered threat

On 16 January 2015, within weeks of Palestine joining, Bensouda opened a preliminary examination into what in the legalese of the court was called “the situation in Palestine”. The following month, two men who had managed to obtain the prosecutor’s private address turned up at her home in The Hague.

Sources familiar with the incident said the men declined to identify themselves when they arrived, but said they wanted to hand-deliver a letter to Bensouda on behalf of an unknown German woman who wanted to thank her. The envelope contained hundreds of dollars in cash and a note with an Israeli phone number.

“If Fatou Bensouda spoke to any person in the West Bank or Gaza, then that phone call would enter [intercept] systems,” one source said. Another said there was no hesitation internally over spying on the prosecutor, adding: “With Bensouda, she’s black and African, so who cares?”

The surveillance system did not capture calls between ICC officials and anyone outside Palestine. However, multiple sources said the system required the active selection of the overseas phone numbers of ICC officials whose calls Israeli intelligence agencies decided to listen to.

Officials also became aware of specific threats against a prominent Palestinian NGO, Al-Haq, which was one of several Palestinian human rights groups that frequently submitted information to the ICC inquiry, often in lengthy documents detailing incidents it wanted the prosecutor to consider. The Palestinian Authority submitted similar dossiers.

Such documents often contained sensitive information such as testimony from potential witnesses. Al-Haq’s submissions are also understood to have linked specific allegations of Rome statute crimes to senior officials, including chiefs of the IDF, directors of the Shin Bet, and defence ministers such as Benny Gantz.

Years later, after the ICC had opened a full investigation into the Palestine case, Gantz designated Al-Haq and five other Palestinian rights groups as “terrorist organisations”, a label that was rejected by multiple European states and later found by the CIA to be unsupported by evidence. The organisations said the designations were a “targeted assault” against those most actively engaging with the ICC.___
