Refugees have high rates of mental health morbidity as a result of conflict. However, their needs for mental healthcare and psychosocial support are often unmet, despite the efforts of professional and humanitarian organisations. The war refugee crisis is a global challenge that needs a global solution. We call on all governments, regional and international organisations to take responsible humanitarian actions to intervene and support people affected by these disasters and for all humanity to unite against the forces of injustice and degradation. The thematic papers in this issue report on the Syrian crisis from a variety of perspectives.
