The Pentagon spent the weekend notifying service members who appeared on an Islamic State (ISIS) “hit list”, CBS News reported on Monday.

Bases where these members are stationed have contacted local law enforcement agencies in an effort to increase police patrols in the neighborhoods where they live, according to the report.

In addition, after being asked by the Pentagon, YouTube took the hit list down from its website.

Hackers affiliated with ISIS published a “hit list” Saturday night of 100 American military personnel. The group, which calls itself the Islamic State Hacking Division, included names, units, addresses and photos of the service men and women from the U.S. Air Force, Navy, and Marines.

Calling for a “jihad against the crusaders,” the post urges ISIS followers to kill the soldiers, who allegedly took part in bombings of ISIS targets in Iraq, Somalia, Syria, Afghanistan, and Yemen.

Pentagon officials said the list appears to be drawn from public sources — everything from newspaper interviews to Facebook pages that connected them, sometimes incorrectly, with the war against ISIS.

“This is very disconcerting, obviously, to the families,” Gen. Carter Ham said, according to CBS News. “The specific families that were identified in this release, but more broadly across the armed services, that those who engage in social media, that that information now can be corrupted and used by a terrorist organization to threaten them.”

There are about 180 Americans who are known supporters of ISIS but there’s no way of telling how many other radicals might be inspired to act by the ISIS list, noted the report.
