European Union governments cannot pick and choose whether to execute arrest warrants issued by the International Criminal Court against two Israeli leaders and a Hamas commander, the EU’s foreign policy chief said on Saturday. The ICC issued the warrants on Thursday against Israeli Prime Minister Benjamin Netanyahu, his former defence minister Yoav Gallant and Hamas leader Ibrahim Al-Masri, for alleged crimes against humanity. All EU member states are signatories to the ICC’s founding treaty, called the Rome Statute. Several EU states have said they will meet their commitments under the statute if needed, but Hungarian Prime Minister Viktor Orban has invited Netanyahu to visit his country, assuring him he would face no risks if he did so. “The states that signed the Rome convention are obliged to implement the decision of the court. It’s not optional,” Josep Borrell, the EU’s top diplomat, said during a visit to Cyprus for a workshop of Israeli and Palestinian peace activists.
