In exchange: ISIS is also demanding the release of neuroscientist Aafia Siddiqui. The ransom was confirmed by a spokesman for Siddiqui's family, who are trying to distance themselves from the group
News of the ransom comes just a week after the group beheaded Foley in a savage propaganda video posted online.
At the end of the video, the group threatened to kill another hostage, journalist Steven Sotloff, next.
The ransom was revealed Monday, at a press conference held on behalf of Siddiqui's family, who are trying to distance themselves from ISIS.
It was also confirmed through a close friend of the unidentified hostage's family.
The group previously asked for the released of Siddiqui when they sent Foley's family a $132million ransom request before his execution.
Siddiqui, an MIT-trained neuroscientist, was convicted in 2010 of trying to kill U.S. officials. Authorities believe she may have also been planning to construction dirty bombs to be used in terrorist attacks.
Her family has released a statement saying they have no connections to ISIS and that 'associating Aafia's name with acts of violence is against everything we are struggling for'.
'While we deeply appreciate the sincere feelings of those who, like us, wish to see the freedom of our beloved Aafia, we cannot agree with a "by any means necessary" approach to Aafia’s freedom.
