Muslims constitute 8% of Frances population.
LILLE, France (Reuters) - Vandals desecrated 148 graves in the Muslim section of a military cemetery in northern France, hanging a pig's head on one of the headstones, police said on Sunday.
French President Nicolas Sarkozy called the attack "a hateful act" and around 100 police were sent to the Notre-Dame de Lorette cemetery near Arras to hunt for clues.
State prosecutor Jean-Pierre Valensi said the vandals struck overnight, daubing insults on the graves.
"They directly referred to Islam and there were also insults directed at the justice minister," Valensi said, referring to Rachida Dati, whose parents came from North Africa.
The desecration came almost exactly a year after youths daubed Nazi inscriptions and swastikas on Muslim tombs in the same cemetery in Ablain Saint-Nazaire.
