According to a FOX news report, Iraqi Security Forces repelled an attack by ISIS on an air base in Anbar province. Reports were that more than 300 Marines training Iraqis might be surrounded.
It turns out that the reports were exaggerated. Apparently eight terrorists attempted to break into the facility.
According to FOX news annalist General Jack Keane, the attempt was simply to get headlines. It appears that the U.S. Marines were never in danger.
