Foiled Assassination Attempt on Pro-Palestinian Activist and Within Our Lifetime Co-Founder Nerdeen Kiswani Uncovered in Hoboken, NJ

In Hoboken, New Jersey, law enforcement agencies, including the New York Police Department and the FBI, have thwarted a purported plan to assassinate a pro-Palestinian activist. This information comes from the intended target, authorities, and a criminal complaint that was made public on Friday in Newark.

The operation led to at least one arrest when law enforcement officials executed a search warrant at the intersection of Willow Avenue and Clinton Street in Hoboken.

Alexander Heifler was taken into custody Thursday evening. He faces charges for illegal possession and manufacture of firearms and is accused of planning an attack on Nerdeen Kiswani. Kiswani, a prominent figure in pro-Palestinian movements, is a co-founder of Within Our Lifetime and has organized numerous protests in New York City.

Although the criminal complaint does not specifically name Kiswani, she disclosed on social media that the FBI had informed her she was the intended victim of the alleged plot.

In a public statement, Kiswani declared she would continue her advocacy for Palestinian rights, undeterred by the threats.

An NYPD undercover officer broke the case open after the department identified Heifler online, infiltrated a group chat, developed a relationship and thwarted the plot.

The undercover officer personally witnessed Heifler making the eight Molotov cocktails in Hoboken Thursday which led to his arrest, officials say.

“Heifler also told the (undercover officer) that he had an address where they could hide out after they threw the Molotov cocktails” and discussed a plan to leave the country, the complaint said.

Authorities allege the plan was to throw the Molotov cocktails at Kiswani that night.

Law enforcement believes they stopped an imminent threat and the FBI said there is no threat to public safety.

Hoboken Mayor Emily B. Jabbour released a statement Friday and said there was “no danger to residents and no ongoing threat.”
