A policeman in France has been stabbed during an operation to arrest three women in connection with a car found with gas canisters near Paris’ famous Notre Dame Cathedral last Sunday. Police opened fire after the stabbing in Boussy-Saint-Antoine, southeast of Paris, wounding one of the women. Officials said the suspects were “radicalized” and appeared to have been preparing an immediate attack, BBC reported. In November, 130 people died in Paris in attacks by the self-styled Islamic State terrorist group. A state of emergency has been in place in France since then. The Peugeot 607 was found early on Sunday on the Quai de Montebello, just meters from the cathedral that attracts millions of tourists every year. The car had its hazard warning lights flashing and no number plates, police said. Documents with writing in Arabic were also found in the car, police said. One of the canisters, on the front passenger seat, was empty, and there were no detonating devices inside. A man on the terrorism watch list was arrested on Wednesday as well as an associate of the car’s owner.
