Infamous anti-Israel advocate Mahmoud Khalil made an appearance in New York City on Saturday, citing a purported Hamas militant during a sizable demonstration held in front of the New York Public Library.

Khalil, 30, stood on the library steps and gave a seven minute speech in which he talked about Anas al-Sharif, an Al Jazeera correspondent who was killed during an Israeli missile strike last week.

Israel has said al-Sharif was running a Hamas terrorist cell, which he and Al Jazeera repeatedly denied.

Khalil recalled al-Sharif’s final words and proclaimed to the crowd of roughly 2,000 — at least one of whom was sporting the green headband worn by members of Hamas’ Izz ad-Din al-Qassam Brigades, a wing of the terrorist group in the Gaza Strip — “The time is now, the bridges towards liberation start with us.”

The protestors marched from the library through the streets of Manhattan to Columbus Circle.

The former Columbia University student made national headlines when he was detained by Immigration Customs and Enforcement in March for posing an alleged threat to national security interests.

He was released in late June from a detention center in Louisiana, after a judge declared his arrest unconstitutional.

Khalil came under fire for bizarrely trying to justify the Oct. 7, 2023 massacre that sparked the Israel-Hamas War during an interview with the New York Times.

The grisly attack, which left roughly 1,200 dead and saw 251 abducted, was a “desperate attempt” by Hamas to “just to break the cycle” of the Palestinian plight, he claimed during the Aug. 6 interview.

He also refused to call the attack a “mistake,” but noted that “targeting civilians is wrong.” 

The statements prompted politicians, including Rep. Elise Stefanik, to declare Khalil should be “immediately deported.”

“Naturalized citizenship is an earned privilege of our nation, and he has not earned it. The government should continue taking every lawful step necessary to remove this enemy from the United States,” Brooklyn Assemblyman Kalman Yeger told The Post last week.

Critics lambasted Khalil as a fraud.

“Mahmoud Khalil is not a hero. He’s a f–king shill that so many are romanticizing as some Robin Hood. He’s out here saying my people getting gleefully butchered was worth it and you have idiots in Congress taking selfies with him and crying over him? Please be serious,” one user wrote on X.
