By JOHN LEICESTER (Associated Press) LE PECQ, France (AP) — The attacker slashed at the 24-year-old man with the knife that he used to savagely stab one young child after another. But rather than run, Henri held his ground — using a weighty backpack he was carrying to swing at the assailant and fend off his blade. French media hailed Henri as “the hero with a backpack” Friday after he was shown in a video grappling with the assailant and charging after him during the knife attack that critically wounded four children between the ages of 22 months and 3 years old, and also injured two adults. Henri, a Catholic pilgrim who is touring France’s cathedrals and just happened to be in the Alpine town of Annecy when the attacker rampaged though its lakeside park on Thursday, also got personal words of gratitude Friday from President Emmanuel Macron.
