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.
Israeli intelligence captured the communications of numerous ICC officials, including Khan and his predecessor as prosecutor, Fatou Bensouda, intercepting phone calls, messages, emails and documents.
The surveillance was ongoing in recent months, providing Israel’s prime minister, Benjamin Netanyahu, with advance knowledge of the prosecutor’s intentions. A recent intercepted communication suggested that Khan wanted to issue arrest warrants against Israelis but was under “tremendous pressure from the United States”, according to a source familiar with its contents.
Bensouda, who as chief prosecutor opened the ICC’s investigation in 2021, paving the way for last week’s announcement, was also spied on and allegedly threatened.
Netanyahu has taken a close interest in the intelligence operations against the ICC, and was described by one intelligence source as being “obsessed” with intercepts about the case. Overseen by his national security advisers, the efforts involved the domestic spy agency, the Shin Bet, as well as the military’s intelligence directorate, Aman, and cyber-intelligence division, Unit 8200. Intelligence gleaned from intercepts was, sources said, disseminated to government ministries of justice, foreign affairs and strategic affairs.
A covert operation against Bensouda, revealed on Tuesday by the Guardian, was run personally by Netanyahu’s close ally Yossi Cohen, who was at the time the director of Israel’s foreign intelligence agency, the Mossad. At one stage, the spy chief even enlisted the help of the then president of the Democratic Republic of the Congo, Joseph Kabila.
Details of Israel’s nine-year campaign to thwart the ICC’s inquiry have been uncovered by the Guardian, an Israeli-Palestinian publication +972 Magazine and Local Call, a Hebrew-language outlet.
The joint investigation draws on interviews with more than two dozen current and former Israeli intelligence officers and government officials, senior ICC figures, diplomats and lawyers familiar with the ICC case and Israel’s efforts to undermine it.
Contacted by the Guardian, a spokesperson for the ICC said it was aware of “proactive intelligence-gathering activities being undertaken by a number of national agencies hostile towards the court”. They said the ICC was continually implementing countermeasures against such activity, and that “none of the recent attacks against it by national intelligence agencies” had penetrated the court’s core evidence holdings, which had remained secure.
A spokesperson for Israel’s prime minister’s office said: “The questions forwarded to us are replete with many false and unfounded allegations meant to hurt the state of Israel.” A military spokesperson added: “The IDF [Israel Defense Forces] did not and does not conduct surveillance or other intelligence operations against the ICC.”
Since it was established in 2002, the ICC has served as a permanent court of last resort for the prosecution of individuals accused of some of the world’s worst atrocities. It has charged the former Sudanese president Omar al-Bashir, the late Libyan president Muammar Gaddafi and most recently, the Russian president, Vladimir Putin.
Khan’s decision to seek warrants against Netanyahu and his defence minister, Yoav Gallant, along with Hamas leaders implicated in the 7 October attack, marks the first time an ICC prosecutor has sought arrest warrants against the leader of a close western ally.
The allegations of war crimes and crimes against humanity that Khan has levelled against Netanyahu and Gallant all relate to Israel’s eight-month war in Gaza, which according to the territory’s health authority has killed more than 35,000 people.
But the ICC case has been a decade in the making, inching forward amid rising alarm among Israeli officials at the possibility of arrest warrants, which would prevent those accused from travelling to any of the court’s 124 member states for fear of arrest.
It is this spectre of prosecutions in The Hague that one former Israeli intelligence official said had led the “entire military and political establishment” to regard the counteroffensive against the ICC “as a war that had to be waged, and one that Israel needed to be defended against. It was described in military terms.”
That “war” commenced in January 2015, when it was confirmed that Palestine would join the court after it was recognised as a state by the UN general assembly. Its accession was condemned by Israeli officials as a form of “diplomatic terrorism”.
One former defence official familiar with Israel’s counter-ICC effort said joining the court had been “perceived as the crossing of a red line” and “perhaps the most aggressive” diplomatic move taken by the Palestinian Authority, which governs the West Bank. “To be recognised as a state in the UN is nice,” they added. “But the ICC is a mechanism with teeth.”A person with direct knowledge of Israel’s preparation for the back-channel meetings said officials in the justice ministry were furnished with intelligence that had been gleaned from Israeli surveillance intercepts before delegations arrived at The Hague. “The lawyers who dealt with the issue at the justice ministry had a big thirst for intelligence information,” they said.
For the Israelis, the back-channel meetings, while sensitive, presented a unique opportunity to directly present legal arguments challenging the prosecutor’s jurisdiction over the Palestinian territories.
They also sought to convince the prosecutor that, despite the Israeli military’s highly questionable record of investigating wrongdoing in its ranks, it had robust procedures for holding its armed forces to account.
This was a critical issue for Israel. A core ICC principle, known as complementarity, prevents the prosecutor from investigating or trying individuals if they are the subject of credible state-level investigations or criminal proceedings.
Israeli surveillance operatives were asked to find out which specific incidents might form part of a future ICC prosecution, multiple sources said, in order to enable Israeli investigative bodies to “open investigations retroactively” in the same cases.
“If materials were transferred to the ICC, we had to understand exactly what they were, to ensure that the IDF investigated them independently and sufficiently so that they could claim complementarity,” one source explained.
Israel’s back-channel meetings with the ICC ended in December 2019, when Bensouda, announcing the end of her preliminary examination, said she believed there was a “reasonable basis” to conclude that Israel and Palestinian armed groups had both committed war crimes in the occupied territories.
