11,000 people remain stranded in Idomeni refugee camp at the still-closed Greece-Macedonia border, where conditions have not improved. A Médecins Sans Frontières field psychologist has observed changes in mood and the impact on the psychological state of the camp. Many refugees carrying some post-traumatic experiences are in a very difficult and vulnerable condition. In the early days of the camp people knew they would cross the border, they were in transit, so they had hope and many of their problems were buried; now these problems have come to the surface. Mental health treatment is increasingly important. Optimistic rumours one day and pessimistic rumours the next spread through the camp like wildfire, sparking a tinderbox of desperation. Greek government spokespersons say Idomeni refugees should not believe false rumours that the border will open any time soon.
