>> glor: good evening, i'm jeff glor. this is our western edition of the broadcast. the white house confirmed this afternoon, what isis claimed this morning, american peter kissig has been executed. kassig who was just 26-years-old had been held since last october, he becomes the fifth western hostage beheaded by isis. two other americans and two from britain were previously killed. the newest video, however is much different than before. we have two reports tonight beginning with julianna goldman. >> this is peter edward kassig. a u.s. citizen of your country. >> reporter: like previous isis execution videos, this one features the same black-masked killer with a british accent known as jihadi john. but kassig did not appear kneeling in an orange jump suit befire he was killed and did not make a statement. the 15 minute video also identified the militants location and shows isis soldiers executing syrian officers. there also wasn't an additional western hostage at the end.

national security advisor susan rice briefed president obama on the video board air force one. as he returned home from australia. the 26-year-old's parents released a statement saying they were heartbroken. isis had revealed that they had kassig in october following the beheading of british aid worker allen henning. kassig was an army ranger in iraq and then turned to humanitarian work. he was abducted delivering aid to syrian brutalized by the civil war. he converted to islam while in captivity and changed his name abdul rachman. his parents spent the last several weeks pleading for his release. in an interview from margaret t senan, they shared a letter from their son given to them by a released hostage. >> he said if i go down for this, i want everyone to know i went down for a good cause. what more can you ask?

>> reporter: the video was released the day after the chairman of the joint chiefs of staff, general martin dempsey, made a surprise visit to iraq. he thanked troops and told them the battle against isis was starting to turn but it would be a drawn out campaign lasting several years. >> glor: julianna, thank you. we are joined now by our national security correspondent juan zarate. jaun as julainna noted, this video is different than the ones we've seen before why is that? >> isis is trying to add to the number of beheadings that are portrayed. it may also be that mr. kassig refused to go on camera and propound the propaganda that others had before heir execution. in addition, they are more open who's doing the beheadings. that may be a reaction to the

criticism of the group by not who is doing them and why. worst quality reveals the under degree of stress that doesn't allow them the production value they've had in the past. >> that said when jihadi john revealed the are location, what's being gained by disclosing that are location? remaining in control of territory, pace of the war, by doing this they're being brazen in the face of western pressure. in addition, there is some theological issues at play here. the site of a major war. muslim army against infidels. this is a quest perhaps to inspire their followers. >> glor: juan zarate, thank you very much. >> thanks jeff. >> glor: the latest patient with ebola is critically ill this night. he is being treated in nebraska. here's carter evans. >> reporter: dr. martin salia is in extremely critical condition. on a ventilator to help him breathe.
