Paul,
I feel sure they are, but I did not see a plaque stating that.
The ones in North Afrika are clearly marked. The Italians moved all of their war dead from the North African campaign back to Italy. No one cleaned up the cemetery site in Tripoli so it is a mess of broken monuments.
The German site in Tobruk I photographed and is on my Google Earth site.
