Ebrahim Asgharzadeh

CNN’s Iranian-born chief international correspondent Christiane Amanpour interviewed one of the leaders of the militant group which stormed the U.S. embassy in Tehran in 1979 and held 52 Americans hostage for 444 days for her “Amanpour” program. The interview, along with that of one of the hostages, is set to air this coming Sunday.

Wednesday’s Newsroom program previewed the upcoming episode of Amanpour’s program 12 minutes into the 12 pm Eastern hour, playing clips from the correspondent’s interviews with Jon Limbert, one of the employees of the embassy who spent more than a year in captivity, and Ebrahim Asgharzadeh, a leader of a group which supported Ayatollah Khomeni and held the Americans captive.
