One-year mark of Oct. 7 attack prompts U.S. intelligence warning of violent extremism

A joint federal intelligence bulletin obtained by CBS News warns of potential violent extremism and hate crimes committed in response to the one-year mark of the Oct. 7 attack on Israel by the militant group Hamas and the resulting conflict in Gaza.

The bulletin, authored by FBI, Department of Homeland Security and National Counterterrorism Center, was first disseminated by federal law enforcement to local law enforcement partners late Wednesday. 

The agencies found that the one-year mark of the attack "as well as any further significant escalations" in the Israel-Hamas war "may be a motivating factor for violent extremists and hate crime perpetrators to engage in violence or threaten public safety," the bulletin read.
