The FBI says Jonathan Hunter Kramer, a Pennsylvania man, used social media to distribute propaganda for ISIS and Hamas, share explosives manuals, and discuss potential terrorist attacks including arson, vehicle rammings, drone attacks, shootings, and poisoning food at synagogues. Agents seized a semiautomatic rifle and 190 rounds of ammunition. Authorities say they intervened before any attack was carried out.
The FBI announced Wednesday evening that Jonathan Hunter Kramer, 21, of Pennsylvania, faces charges for allegedly using social media to distribute propaganda for ISIS and Hamas, share manuals for making explosives, and discuss potential terrorist attacks including arson, vehicle rammings, drone strikes, shootings, and poisoning food at synagogues. The suspect was arrested the day after Rosh Hashanah, as The Zioneer first reported. Federal agents seized a semiautomatic rifle, 190 rounds of ammunition, and five 30-round magazines during the investigation. Authorities stressed they intervened before any attack was carried out.
Earlier Wednesday at 09:24 Jerusalem time, The Zioneer reported that a Pennsylvania resident had been arrested over an alleged plot to attack people he called 'infidels.' Shortly after, additional reporting identified the suspect as Jonathan Hunter Kramer and revealed that the plot involved attempts to synthesize cyanide and ricin to inject into food at synagogue events, with a hotel raid yielding weapons and tactical gear. By Wednesday evening, the FBI’s detailed charges confirmed the full scope of the propaganda and planning, including references to ISIS and Hamas and multiple attack methods. The corroboration evolved from an initial local report through identification of the suspect to a comprehensive federal indictment.
As The Zioneer has reported in related coverage, this case fits a growing pattern of federal investigations into online radicalization and lone-actor terrorism on U.S. soil. Earlier this year, the White House UFC assassination plot involved TikTok recruitment and sniper and drone plans targeting top officials, while a Hamas-linked suspect was arrested in Greece over an alleged plot to attack Israeli tourists. In both cases, as with Kramer, authorities emphasized early intervention.
What remains open is whether Kramer had direct contact with terror operatives abroad or was entirely self-radicalized online. The FBI has not disclosed whether additional arrests are expected or whether the investigation extends to other individuals connected to the suspect's online activity.
