Armed with knives, some knowledge of their prey and a large dose of cruelty, attackers are going after horses and ponies in pastures across France in what may be ritual mutilations. Up to 30 attacks have been reported in France, from the mountainous Jura region in the east to the Atlantic coast, many this summer, the agriculture minister said Friday. “We are excluding nothing,” Agriculture Minister Julien Denormandie said Friday on France-Info, before heading to a riding club in the Saone-et-Loire region, in east central France, where a horse was attacked a day earlier.
