France said Monday 'several' of its dual citizens are unaccounted for in Gabon after the deadly unrest that followed the contested re-election of President Ali Bongo.

"Arrests have been carried out in recent days. Several French compatriots are unaccounted for," according to a statement from French Foreign Affairs Minister Jean-Marc Ayrault. 

They are believed to be roughly 10 dual French-Gabonese nationals who cannot be located, according to a diplomatic source.
