“We do not talk politics, but if we evoked the National Front, he would get on his hind two legs and began to growl, says Gaëtan. He claimed to fight against fascism and was very much against the police. He treated the police and the military fascists with an aggressiveness that made me ill at ease. »

Five charged over Jewish grave vandalism in France

The suspects, aged 15 to 17, are accused of the “desecration of burial places due to the religion of the deceased”.

Local prosecutor Philippe Vannier said the vandalism appeared to be part of a game that went wrong.
