(CNN) — Attacks are intensifying against ISIS, the Islamic extremist group that killed James Foley.
The new wave of air strikes come as the family of the murdered American journalist call for another look at the government’s policy not to negotiate with terrorists.
Michael Foley said his brother James had a passion for people and storytelling. In an interview with yahoo.com, Foley described his brother as a brave journalist, even after being captured by ISIS militants.
Foley feels the U.S. could have done more.
While other countries have paid ransom for hostages, Foley’s family wants the government to re-examine its own policies.
“I really, really hope that in some way Jim’s death pushes us to take another look at our approach, our policy to terrorists and hostage negotiations and rethink that,” Michael Foley said.
The Foley family is also making public the last communication they received from their son’s captors.
Dated Aug. 12, a portion of the chilling email reads “you and your citizens will pay the price of your bombings! The first of which being the blood of the American citizen, James Foley! He will be executed as a direct result of your transgressions towards us!”
The venomous email comes after the Defense Department branded ISIS beyond a terrorist group.
The U.S. continues air strikes against ISIS targets in Iraq — each attack meant to disable a terrorist group that’s already shown its brutality.
