New York City Mayor Zohran Mamdani said he is exploring legal avenues to arrest Israeli Prime Minister Benjamin Netanyahu during a potential visit to the city.

The move represents a significant diplomatic escalation, as it challenges the traditional immunity typically granted to foreign heads of state visiting the United Nations.

Mamdani said he is consulting with the New York City Law Department and local law enforcement to determine if he has the legal authority to order the arrest if Netanyahu attends the United Nations General Assembly in September [1]. The mayor's inquiry centers on whether a legal loophole exists to detain the Israeli leader based on allegations of war crimes.

"He’s a war criminal," Mamdani said [1].

The mayor said that Netanyahu may be subject to an arrest warrant from the International Criminal Court [1]. Because the UN General Assembly takes place in New York, the city's administration is reviewing the intersection of local jurisdiction and international law.

"We are in active conversations with local law enforcement to see whether a move can be made if the foreign leader attends the UNGA in September," Mamdani said [2].

Legal experts generally maintain that heads of state enjoy diplomatic immunity while visiting the U.S. for UN business. However, Mamdani said that his administration is specifically seeking a way to bypass these protections to ensure accountability.

"I am still looking into whether I can order his arrest," Mamdani said [1].

The potential arrest remains contingent on the legal advice provided by the city's law department and the specifics of any existing international warrants [1].

"He’s a war criminal."

This situation creates a potential legal and diplomatic crisis between New York City and the Israeli government. While the U.S. State Department typically ensures the safe passage of foreign diplomats to the UN, a city-level attempt to arrest a head of state would test the limits of municipal power versus international diplomatic immunity.
