New York City Mayor Zohran Mamdani said in a brief video address late Tuesday that his administration lacks the "independent legal authority" to enforce an International Criminal Court warrant against Israeli Prime Minister Benjamin Netanyahu, who is wanted for alleged war crimes and crimes against humanity in the Gaza Strip.Mamdani said in his two-minute address that after reviewing "every avenue available under applicable law to determine whether New York City could execute the International Criminal Court’s arrest warrant if Benjamin Netanyahu came here," his administration determined that it did not have the authority to do so."The federal government, however, does—and I call on them to join the ICC and execute this warrant," said Mamdani, who characterized Netanyahu as a "war criminal" and "the architect of a horrific genocide against the Palestinian people.""Benjamin Netanyahu is not welcome in New York City, nor is any other war criminal at large," said the New York City mayor, who—according to one recent poll—is more popular with Jewish adults in the US than the Israeli prime minister. "While we cannot end the genocide on our own, we can decide whether our silence will become another weapon, and we can examine every tool we have to defend the humanity and dignity of all people."Watch Mamdani's full remarks: Mamdani said during his 2025 mayoral campaign that, if elected, he intended to pursue Netanyahu's arrest should the Israeli prime minister set foot in New York City. Netanyahu is expected to be in the city in September for the United Nations General Assembly.US President Donald Trump said earlier this week that Netanyahu would "not be arrested, in any way, shape, or form, while in the United States of America."Neither the US nor Israel are party to the treaty that established the International Criminal Court, and the US State Department earlier this month launched an effort to "dismantle" the ICC, which is tasked with investigating and prosecuting individuals for war crimes.Mamdani said in his address on Tuesday that Netanyahu is "responsible for the killing of more than 73,000 people, for the maiming of tens of thousands of children as those who survive undergo amputation without anesthesia, [and] for the targeting of neonatal hospitals and maternity care centers, denying newborns even the chance to live."The mayor also cited a recent UN report accusing the Israeli military of deliberately targeting children in Gaza."The list goes on and on. All as we, as Americans, pay for the bombs that do the killing," said Mamdani. "I agree with the ICC that Benjamin Netanyahu should be arrested and tried for his crimes, as I do for anyone else charged by the ICC."
