French President Emmanuel Macron is honouring victims of the Paris terror attacks of 2015 as a key jihadist's silence frustrates investigators.
The only jihadist suspect to have survived the night of carnage, Salah Abdeslam, is being held in solitary confinement and is on suicide watch.
He is believed to have handled logistics for the group which attacked a stadium, cafés and a nightclub.
But French media report that he has only spoken once, sticking to his right to silence, despite having faced judges six times.
Investigators say the dossier against him may not be completed until the spring of 2019, French BFMTV reports.
Mr Macron is attending ceremonies at the places targeted by the jihadists, whose carnage was claimed by so-called Islamic State (IS).
The first ceremony was at the national stadium - the Stade de France - where three suicide bombers blew themselves up outside after failing to get into a France v Germany football match.
Ex-President Francois Hollande, who was at the game, is accompanying Mr Macron.
