NBC: Islamic State Is Collecting Foreign Hostages

A day after news broke that the Islamic State beheaded American journalist James Foley, NBC News’ senior foreign correspondent has grim news of the near-term future.

According to Engel, IS terrorists are going about capturing foreigners and trading for them, building a cache of foreign hostages. Engel says the group already has between 30 and 40 western hostages.

IS is still holding American Steven Sotloff. The group tweeted out images of him Tuesday, and warned that his life depends on what President Obama does next.
