Razan Zaitoudeh disappeared December 2013 from her home. It is probably not realistic to ask or expect her release. It is more likely that she was murdered.
Earlier in her life, Razan was detained by the Syrian government. At the time Amnesty International campaigned for her release.
Razan, Samira, Wael and Nazem disappeared together. This has been documented using the P746, date of disappearance property for all of them.
Together they received the Petra Kelly award. I am sure that their loved ones would prefer them to be safe instead.
