Hungary will start the process to withdraw from the International Criminal Court, an official said Thursday, just as Israeli Prime Minister Benjamin Netanyahu arrived to red carpet treatment in the country’s capital despite an arrest warrant from the world’s only permanent global tribunal for war crimes and genocide.

Prime Minister Viktor Orbán gave the Israeli leader a welcome with full military honors in Budapest’s Castle District. The two close allies stood side by side as a military band played and an elaborate procession of soldiers on horseback and carrying swords and bayoneted rifles marched by.

As the ceremony unfolded, Orbán’s chief of staff, Gergely Gulyás, released a brief statement saying that “the government will initiate the withdrawal procedure” for leaving the court, which could take a year or more to complete. Netanyahu’s visit to Hungary, which is scheduled to last until Sunday, was only his second foreign trip since the ICC issued the warrant against him in November.

The ICC, based in The Hague, Netherlands, said when issuing its warrant that there was reason to believe Netanyahu and former Israeli Defense Minister Yoav Gallant had committed crimes against humanity in connection with the war in Gaza.

The war began when Hamas-led militants attacked southern Israel on Oct. 7, 2023, killing around 1,200 people, mostly civilians, and taking 251 hostages, most of whom have since been released in ceasefire agreements and other deals. Israel rescued eight living hostages and has recovered dozens of bodies.

Israel’s offensive has killed more than 50,000 Palestinians, according to Gaza’s Health Ministry, which doesn’t say whether those killed are civilians or combatants. Israel says it has killed around 20,000 militants, without providing evidence. Israeli military’s response resumed last month, shattering a ceasefire.

After the ICC issued the warrant, Orbán invited Netanyahu to Budapest, and accused the court of “interfering in an ongoing conflict for political purposes.” That invitation was in open defiance of the court’s ruling and contradicted Hungary’s obligations as a signatory to arrest any suspects facing a warrant if they set foot on their soil.

All countries in the 27-member European Union, including Hungary, are signatories, but the court relies on member countries to enforce its rulings. Hungary joined the court in 2001 during Orbán’s first term as prime minister.
