KITTERY, Maine — Vice President Joe Biden says America will follow the terrorists who have killed two journalists "to the gates of hell."
Speaking at the Portsmouth Naval Shipyard in Kittery, Maine, Biden said Wednesday that the Islamic State militant group responsible for beheading Americans James Foley and Steven Sotloff won't intimidate the United States.
Biden said the American people "are so much stronger, so much more resolved" than any enemy can understand. He says the U.S. won't stop until the militants are brought to justice.
Biden said: "Hell is where they'll reside."
A videotape showing Sotloff's slaying was broadcast Tuesday, two weeks after the same group released a video showing Foley's slaying.
The militants said the killings were in response to U.S. airstrikes against the group in Iraq.
