Preface 9 HUMANS WITHOUT RIGHTS “Warsheh” team for advocacy and documentation has been working on the issue of Syrian statelessness since 2017 by monitoring cases of women married to foreign fighters who entered Syria in order to fight against the Syrian regime. After several questionnaires and meetings of the initiative team inside Syria, it became clear that the problem is not only the statelessness of children as a result of marriage to foreign fighters, but also their loss of lineage. Therefore they are undeclared and do not have the most basic rights, especially because their fathers are unknown in name and lineage in most cases. In addition, the entry of foreign fighters to fight in Syria, did not only take place in areas outside the control of the regime, but also included the entire Syrian territory, as many foreign fighters entered to fight alongside the regime as well. The initiative also monitored cases of Syrian female survivors who were raped inside detention centers, which resulted in the birth of children to unknown fathers, who will not be recognized by the Syrian regime as it will confirm one of the crimes committed in its detention centers against female detainees. Here, we have to recall that the use of rape as a weapon is not limited to the regime’s detention centers, but it was used in all detention facilities in Syria, according to many testimonies obtained by the team.
