French police have carried out dozens more raids on addresses across the country after Friday's attacks – making 23 arrests.
The military's also been bombing Islamic State targets in Syria for a second night.
Meanwhile stories are emerging of people who survived the attacks, with residents and visitors to the city reflecting on the tragedy.
Nora Hickey is director of the Irish Cultural Centre in Paris, where 35 Irish students are staying for the year.
She explains her reaction to the attacks on Friday night.
The centre has just 12 staff, one of whom was at the Bataclan concert venue, where 80 people were murdered.
Trinity College Dublin have sent over a Counsellor and a lecturer to help the students.
This morning, President Hollande met the US Secretary of State to discuss a common response to the attacks, ahead of a meeting with Obama in Washington next week.
John Kerry said there was a common plan in place to attack Islamic State.
Nora Hickey says that's worrying.
