American journalist Steven Sotloff has been executed by the Islamic State of Iraq and Syria (ISIS), the group claims in a purported video released Tuesday.
Sotloff, who freelanced for Time and Foreign Policy magazines, had last been seen near Turkey-Syria border in August 2013, when he vanished without a trace.
He then appeared a video released online last month by the Islamic State group that showed the beheading of fellow American journalist James Foley.
Dressed in an orange jumpsuit against the backdrop of an arid Syrian landscape, Sotloff was threatened in that video by the masked man who killed Foley.
The executioner called out U.S. President Barack Obama personally that unless the U.S. stopped air strikes on ISIS, Sotloff and more Americans would die.
