The Pentagon has identified three of the four Americans killed in a suicide bomb attack claimed by the Islamic State group in Syria this week.

They are Army Chief Warrant Officer 2 Jonathan R. Farmer, 37, of Boynton Beach, Florida, who was based at Fort Campbell, Kentucky; Navy Chief Cryptologic Technician (Interpretive) Shannon M. Kent, 35, from upstate New York and based at Fort Meade, Maryland; and a civilian, Scott A. Wirtz, from St. Louis.
