France would be living with the threat of terror attacks “for a long time”, he said.
Valls said he was struck by the fact that young people had been targeted in Friday’s attacks on a concert hall, bars and restaurants and outside theStade de France stadium that left 129 people dead.
“Once again the terrorists have attacked France, the French people, young people. Many young people are dead,” he said.
