Mathilde Panot of LFI (La France Insoumise, Eds.), Olivier Faure of the Socialist Party and Marine Tondelier, leader of the EELV (Green) party, express their "horror" after the knife attack at a secondary school in Arras that left one person dead, and called for the country to "unite". Faure says the attack has "reawakened in all of us this horror and the need to fight against the Islamist hydra that is wreaking havoc in our country and elsewhere". IMAGES AND SOUNDBITES
