Departing from its serial beheading videos of Western hostages that have outraged the world, the Islamic State group released a new video Thursday featuring a captive British journalist, seated behind a desk, explaining the group's message and warning that America and its allies are foolishly heading into another unwinnable war. The Internet video, titled "Lend Me Your Ears" and subtitled in Arabic, shows the journalist, John Cantlie, dressed in an orange jumpsuit and apparently reading from a script, recalling how he was captured by the militant group after he arrived in Syria in November 2012.
