ISIS has murdered a second American reporter, releasing another video Tuesday showing a masked militant with a British accent cutting the throat of a US captive.
Word of Mr. Sotloff’s beheading came two weeks after James Foley, another American journalist, was beheaded by ISIS.
The White House and State Department said intelligence officials are working quickly to determine the video’s authenticity. If it is genuine, State Department spokeswoman Jen Psaki said, “We are sickened by this brutal act.”
U.S. lawmakers on both sides of the aisle urged tough and swift action in response.
