Mental health problems are “huge” in conflict or emergency settings, with more than one in five people affected, the World Health Organization (WHO) has said in a new report. 

After reviewing data from 39 countries and territories, the UN health agency estimates that one in 10 vulnerable people has a moderate to severe mental disorder, which can be life-threatening. 

In an interview with UN News’s Daniel Johnson, WHO’s Dr. Mark van Ommeren outlines the findings and describes what’s being done to help sufferers, including in war-torn Syria.
