This Dailymail article claims this:
Some 3,400 children ran among the graves of soldiers who died in the battle of Verdun as part of a stunt choreographed by German filmmaker Volker Schlondorff, who argued that he was 'trying to depict the chaos of the battle'
I find it hard to believe that the people in charge would agree to this. Also, perhaps it's only me, but the pictures look fake. Lastly, I couldn't find other verifiable sources of this claim.
Did people run through the military graveyards at Verdun?
