ISIS 'Kill List' Targets U.S. Military Members, Posting Names, Addresses and Photos

U.S. federal authorities are investigating the Islamic State's so-called "kill list," which allegedly includes the names, addresses and photos of members of the American military, a Fox News report.

The report said one military spouse said she heard from someone from the Naval Criminal Investigative Service, or N.C.I.S., telling her family to be vigilant.

The wife, who requested anonymity, told Fox News that the information posted by ISIS sympathizers is true.

"We had a call from an N.C.I.S. agent on Saturday who said we were on the 'ISIS kill list,'" she told Fox News. "The agent wanted to verify our name and address as accurate. He said the threat should be considered. We need to be vigilant, but there was no guidance on what to do and no meeting in person to do a security assessment of our home."

She said some of the names on the list were related to the United States' campaign against ISIS in Iraq and Syria.

They said the photos were sourced from open source materials.

White House Press Secretary Josh Earnest said no information system was hacked and the information was taken from social media.

Earnest said the F.B.I. is leading the investigation into the matter. "We obviously take the safety and security of our military personnel very seriously," he said.

The military wife, however, said "the way it is being presented implicates the service members when, in fact, many of these photos were published by the Navy PR machine."

She is wary about letting her children out of the house. "I don't know whether to let our kids play basketball out front of the house," she said. "I don't know if we can get housing on base. But moving onto base would be letting ISIS intimidate us and win."

A defense official was quoted by Fox News as saying that "each service is doing notifications for service members whose IDs were posted by ISIS/ISIS affiliated hackers," and that Twitter and YouTube agreed to take down the posting.

"The safety our service members is always a concern. We always encourage our personnel to exercise appropriate [operational security] and force protection procedures," the defense official said.
