The family of US journalist Steven Sotloff have spoken publicly for the first time since a video of his beheading was released by militants.
They said that the reporter gave his life to covering the suffering of people in war zones, but was “no hero”.
Mr Sotloff “tried to find good concealed in a world of darkness”.
Vice President Joe Biden said that Islamic State militants who killed him and another US man, James Foley, would be pursued “to the gates of hell”.
