There are some 10,000 people in an unofficial refugee camp in Idomeni, Greece. Many have been living at the camp for months, essentially in limbo.
As Jeanne Carstensen reports in this broadcast, months of waiting and desperation can make tempers flare. That's what happened last night in Idomeni, and police responded with tear gas.
Photographer Jodi Hilton, who has been reporting from the camp this week, witnessed what happened and sent us these images.
