French 'Backpack Hero' Fights Knifeman After Children Stabbed.

A young Catholic pilgrim, known as the "backpack hero," is being hailed in France for his bravery in confronting a man who stabbed several children in a park in Annecy. Henri, a 24-year-old management and philosophy student, used his backpack to try and block the attacker and pursued him into the playground. The attacker, a Syrian refugee, stabbed four toddlers and two pensioners before being arrested. Henri's social media accounts have been flooded with messages of thanks for his actions.
