It is captioned "Palestinian prisoner" and appears to show an AFP photo of IDF soldiers abusing a Palestinian Arab.
However, it was no such thing.
As the French IDF blog notes, the "soldiers" were not wearing standard IDF uniforms or helmets.
In fact, this photo was taken at a demonstration on Land Day in Lebanon! The actual caption from AFP read:
Palestinian refugees pose as Israeli soldiers arresting and beating a Palestinian activist during celebrations of Prisoners' Day at the refugee camp of Ain el-Helweh near the coastal Lebanese city of Sidon on April 17, 2012.L'Express silently removed the photo with the offending caption from its website without an apology.
Par for the course.
