The family of the British ISIS hostage have pleaded to the militant group to "make contact," NBC News reported. Relatives of David Haines released a short statement on Saturday in an appeal for the terror group to send a response. "We are the family of David Haines," it reads. "We have sent messages to you to which we have not received a reply. We are asking those holding David to make contact with us." Haines, 44, was named as ISIS' next target in a video showing the beheading of American journalist Steven Sotloff and was shown kneeling in the sand next a member of ISIS.
