New York City Mayor Zohran Mamdani said the city cannot arrest Israeli Prime Minister Benjamin Netanyahu and urged the federal government to act [1].

The statement comes as the International Criminal Court has issued a war-crimes warrant against the prime minister. The tension between local and federal authority highlights a legal conflict over whether the U.S. will honor international warrants for foreign heads of state.

Mamdani made the announcement on July 22, 2026 [1]. He said that the city lacks the legal jurisdiction to detain a foreign leader, but argued that the federal government possesses the necessary authority to do so [2].

"New York City cannot arrest a foreign head of state, but the federal government can," Mamdani said [1].

Netanyahu is scheduled to visit the city in September 2026 [3] for the United Nations General Assembly. Mamdani said that the U.S. government should use this opportunity to align with international law.

"The federal government, however, does. I call on them to join the International Criminal Court..." Mamdani said [2].

The request for an arrest has been met with a firm rejection from the executive branch. Donald Trump said via a social-media post that Netanyahu will not be arrested in any way, shape, or form while in the United States of America [3].

This clash of positions creates a diplomatic friction point ahead of the September summit. While the mayor seeks to signal support for the ICC's findings, the federal administration has signaled that it will provide full protection, and immunity, for the Israeli leader during his stay in the U.S. [3].

New York City cannot arrest a foreign head of state, but the federal government can.

This dispute underscores the legal gap between municipal authority and federal sovereignty regarding diplomatic immunity. While Mayor Mamdani is utilizing his platform to advocate for international judicial accountability, the federal government's refusal to act confirms that the U.S. will prioritize its bilateral relationship with Israel and the principle of head-of-state immunity over the warrants issued by the International Criminal Court.
