Overview
- Mamdani told The New York Times in an interview published Saturday that his administration is in an active conversation with the New York City Law Department about whether the city can lawfully detain Prime Minister Benjamin Netanyahu if he comes for the UN General Assembly in September.
- He called Netanyahu a "war criminal" and cited the ICC arrest warrant issued in 2024 as the basis for his interest in possible enforcement by city authorities.
- Legal experts and multiple U.S. and state officials say the idea faces steep barriers, noting the United States is not a party to the ICC, the U.N. Headquarters Agreement and customary head‑of‑state immunity protect visiting leaders, and federal authority over foreign affairs would likely preempt a mayoral action.
- Netanyahu dismissed the threat and accused Mamdani of siding with Hamas, Israel's U.N. ambassador Danny Danon sharply rebuked the mayor, and U.S. Ambassador to the U.N. Mike Waltz called the proposal "pure political theater," while Governor Kathy Hochul said the mayor likely lacks the power to carry it out.
- The dispute intensifies an already public feud over Gaza accountability and could complicate security and diplomatic planning for UNGA week, but reporting and legal commentary across outlets emphasize the proposal is politically charged and legally unresolved rather than a likely immediate action.
