The NYPD and the FBI said they have disrupted an alleged plot to kill a Palestinian activist, according to law enforcement officials and unsealed court documents.

Authorities arrested Alexander Heifler in Hoboken on Thursday night on charges of unlawfully possessing and unlawfully making firearms. He is also accused of plotting to “go after” activist Nerdeen Kiswani, co-founder of Within Our Lifetime, who is an organizer of many of the pro-Palestinian protests in New York City.  

Kiswani is not identified by name in the criminal complaint, but she posted on social media the FBI informed her she was the alleged target.
